With 50 days to go until the start of the 2015 , teams are inching closer to the final stages of their preparation for the big event. In honor of the 50-days-out mark, here are my rankings of the 50 most intriguing prospects available this year. These aren't nece sarily the top talents in the draft, but each piques my interest more than the average player. Full draft profiles on this year's prospects are available .1. , DL, USCThe skinny: Has ideal frame and can play in almost any spot along the defensive line. Tape is good, not great, but his raw talent and projection have teams excited.2. , LB, TCUThe skinny: His college numbers were off the charts in all of the "big-play" metrics, but his NFL performance was so bad that the battle between tape/traits will be intriguing.3. , WR, UCFThe skinny: Has quickne s and long speed, which is somewhat rare for big WRs. Had too many drops, but shows traits of a big-time WR. Is he an early round projection or an overdraft waiting to happen?4. , OT, PittsburghThe skinny: Former defensive end turned offensive tackle has outstanding feet. He struggled at the , but has a ma sive set of tools and traits. Can he unlock them?5. , OLB, KentuckyThe skinny: Has good play strength and is a freakish athlete with an explosive leaping ability and 40-yard dash time for a 269-pound player, but his tape doesn't show consistency. Is he just waiting to be coached?6. , OLB, FloridaThe skinny: Finally settling into a position. Fowler has seen his weight fluctuate based on where he was playing. Flashes explosive traits and likely will be the first OLB/DE off the board.7. , RB, IndianaThe skinny: Has blazing speed on tape. Some scouts dismi s him because he doesn't have much "wiggle," while others see a game-changer. Posted huge production behind an average line.8. , DE/OLB, Mi souriThe Blank Jersey skinny: Doesn't have the length teams look for at DE, but plays with enough toughne s for the position. Will Ray's production in college trump 's traits?9. , DL, OregonThe skinny: He finally committed to football after also playing basketball at Oregon. Armstead has violent hands/power with prototype 3-4 DE size. He's ascending, but how high will he go?10. , NT, ClemsonThe skinny: He's a short fireplug, but always winning leverage battles in space. After the succe s of last season, teams likely will look at Jarrett differently. Few blocked him at the .11. , CB, Florida StateThe skinny: High school track man who showed it again at the combine. He had good workouts and might have had a better 2014 season than the more heralded Seminoles corner in this year's draft, P.J. Williams.12. , DE, UCLAThe skinny: Posted freakish combine numbers. I get the feeling that he's still figuring his talent out and learning how to use it. He might go much higher than expected, and po sibly in the first round.13. , DE, UtahThe skinny: Former WR turned DE. Scouts differed on his toughne s, but he showed some strength at the . Orchard was a one-year wonder at Utah. Outlier or the real deal?14. , RB, GeorgiaThe skinny: If he didn't have ACL injury, he is likely the first RB off the board and would go in the first round. Are teams willing to bet on him after the quick recoveries of and ?15. , WR, Arizona StateThe skinny: He doesn't get much separation in short-area routes, but scouts swear by him. Former basketball player with leaping ability and good timed speed. On the move.16. , QB, Florida StateThe skinny: He can make all the throws and has an NFL frame and played with some NFL offensive concepts, but he's an interesting test case in maturity after 's i sues.17. , OLB/S, WashingtonThe skinny: Interesting because he's a really good athlete, but what will he weigh and where Ken Griffey Jersey will he play? Can he play both OLB and safety or does he lack a position?18. , CB, LSUThe skinny: Size and speed traits, but doesn't have the starting experience of some others at his position in this draft. Comes from serious NFL stable of CBs at LSU.19. , LB, ClemsonThe skinny: Great workout and solid tape. Moving up draft boards quickly. One of several talented defensive players at Clemson. Could be a top-50 pick.20. , CB, Miami (Ohio)The skinny: Outstanding feet and potential after only one year of college football, but he didn't run fast and teams must decide whether to keep him at CB or move him to safety.21. , RB, NebraskaThe skinny: Tons of fumbles, incredible personal and football character, outstanding vision and cutback ability but limited by size. How high does he go? Second round? Third?22. , RB, AlabamaThe skinny: Scouts are divided on Yeldon. Some say he doesn't hit enough big plays. Others see him as a top-four back in this draft. Has a big frame with limited tread off tire and excellent vision.23. , DT, IndianaThe skinny: I haven't heard many talking about this guy, but his tape is really good. Spoke Art Warren Jersey with a friend in the league who also likes him.24. , G/C, HobartThe skinny: Was the first Division III player invited to the and he held his own. Stronger than expected at combine with great feet. Should go inside first three rounds.25. , S, SamfordThe skinny: Small-school safety with big-school size. Physical and didn't seem rattled or in awe against better competition in college. He made colleague of the top five safeties in the draft.26. , WR, GeorgiaThe skinny: Made big plays in Georgia's run-happy offense, but has flown under the radar. His combine tests were eye-popping but he dropped tons of pa ses in his workout.27. , DT, IowaThe skinny: Played with pa sion last season and flashed at the . Has great size and good quickne s. Some teams could rank him as one of the top three DTs available.28. , WR, AuburnThe skinny: Looks great on the hoof, with long legs and ability to crank up to top speed and threaten deep. Had way too many drops, though. Can he be more than just a vertical WR?29. , DE, LSUThe skinny: The traits are all there on tape, but he hasn't been able to put them together for consistent production. Can anyone unleash it?30. , LB, Miami (Fla.)The skinny: His workout matched his tape for the most part -- it was good, but not spectacular. Some people swear by him and his ability to own the box, but can he play three downs?31. , OT, North Carolina StateThe skinny: Very good athlete who moved exceptionally well in space during combine drills. Dealt with injuries over two-year period, but might be a steal in middle rounds.32. , CB, USCThe skinny: Mi sed much of the 2014 season while serving suspension. Good size. Ran really fast, but teams must figure out if he is a CB or safety and whether he plays as fast J.P. Crawford Jersey as he was timed.33. , TE, Florida StateThe skinny: Doesn't look the part -- short arms, relatively unathletic and wasn't impre sive in combine testing, but catches everything, is tough, doesn't wear gloves and is golf legend Jack Nicklaus' grandson.34. , CB, Texas StateThe skinny: Plays angry with great motor and quick twitch. Adversity shaped his background and plays with a chip on his shoulder. Tested well at combine.35. , CB, Mi si sippiThe skinny: Have to weigh productivity vs. height at CB. Had incredible on-ball production and is a quick-twitch athlete but he's short. How soon do you draft him?36. , DT, Tenne see-ChattanoogaThe skinnny: Older prospect who was a transfer player. Has a more mature game already. Might be able to come in and get snaps quickly.37. , OLB, North Dakota StateThe skinny: Amazing production for four-time national champion. Doesn't have length or eye-popping measurables, but tape is strong and his motor is on point.38. , DT, Central MichiganThe skinny: Late bloomer. High school baseball star. Big frame and flashed at East-West Shrine Game practices. Teams are talking about him.39. , WR, Georgia TechThe skinny: Big wide receiver with limited production. Got his shot after DeAndre Smelter went down for the Yellow Jackets. Ran faster than expected at combine.40. , WR, William MaryThe skinny: Can make circus catches that will blow you away. Outstanding body control, but no way he plays as fast as his timed combine speed. Played against a lower level of competition in college.41. , QB, BaylorThe skinny: As teams continue to write "system QBs" out of early draft contention, it will be interesting to see if Petty can be the guy who acclimates to an NFL offense quickly.42. , WR/TE, MichiganThe skinny: With his slow 40 time (4.70), teams are going to have to lock in on him as a move tight end, but is he physical enough to handle any real blocking? How badly did he hurt his stock?43. , OT/G, TCUThe skinny: Ma sive tackle/guard prospect with power and decent feet. If he can get his weight down another 10-15 pounds, he might take a big step forward.44. , CB/S, Western MichiganThe skinny: Nobody in college football had more pa ses defensed. Doesn't run well and isn't a great athlete, but has great instincts and ball skills. Move to safety could be key.45. , OLB, Oregon StateThe skinny: Spoke to coach who brought him up. Said his athleticism is rare and loves the fact that he's a former track guy and wide receiver who is moldable.46. , OLB/DE, MiamiThe skinny: Wrote him off early in my appraisal, but he flashed at East-West Shrine Game practices and had a good combine. Future might be at OLB, Edwin Diaz Jersey of all places.47. , OT, Notre Dame CollegeThe skinny: Big, athletic player who dominated lower level. Has holes in his game, but his potential and athleticism will have teams very interested.48. , CB, AuburnThe skinny: Moving from QB to former position of CB. Clearly behind others at working at corner, but had some moments. Desired size, but how long is learning curve?49. , DT, Lincoln (Mo.)The skinny: Kicked off the Syracuse football team after being charged with burglary (he later pled guilty). Destroyed the competition at Lincoln University. Has some traits and talent that are translatable to league.50. , ILB/FB, CincinnatiThe skinny: Productive, old-school inside linebacker who is built like a fire truck. I see him as a fullback. Reminds me of former NFL player Vonta Leach. Played some fullback in high school.Follow Lance Zierlein on Twitter .
