NFL Draft Top 50, Nos. 11-20: Top offensive tackles lumped together

Shutdown Corner has compiled information from teams, watched college tape and gathered our notes from the Senior Bowl and NFL scouting combine to assemble our top 50 overall prospects available in the 2015 NFL draft.

We'll roll our list out 10 players at a time this week, counting backward from 50 (along with those who just missed the cut). Please note: These are the best players available — and not where we think the prospects will be drafted.

11. Louisville WR DeVante Parker 
6-3, 209

Missed part of the 2014 season with a broken bone in his foot but came back like gangbusters, hardly showing rust in catching 43 passes for 855 yards and five touchdowns in only six games. Carved up an FSU secondary that includes two high picks at cornerback this year and a future star in Jalen Ramsey, catching eight passes for 214 yards. Parker is not a blazer but is excellent after the catch, has exceptional hands and can play above the rim with his height and his 33-inch arms. Although the injury cost him a step and he sometimes has to gear up to top speed, Parker is an extremely natural and graceful receiver who will make plays in almost any kind of passing game.

12. Clemson OLB-DE Vic Beasley
6-3, 246

The Tigers' all-time leading sacker with 29 has plenty of great tape the past few seasons, showing his burst off the snap, the ability to dip his shoulder and attack quarterbacks. Beasley also has a knack for the strip sack, can get bigger tackles off balance with his speed and has very active hands. Made incredible postseason gains, adding weight (more than 20 pounds), shaving time off his 40-yard dash and turning in a few head-turning results in the combine testing. Only played about 40-45 snaps per game the past two seasons and might need to be subbed out in obvious running situations. Beasley also played at closer to 220 pounds by the end of last season and must show he can maintain this new weight over the course of the season.

NFL comparison: Robert Mathis

Draft range: Top 15 pick

13. LSU OT-OG La'el Collins
6-4, 305

Mean-streaked masher who has improved steadily over the past two years at left tackle but who could project quite easily to guard in the NFL, as well. Collins plays with some vinegar and shows a propensity to learn from (and not repeat) his mistakes. Competitive, smart worker who speaks softly but carries a big stick. Not massive but well-built with a barrel chest and sufficient arm length to play outside. Collins can get caught lunging and bending and might need some live bullets to get adjusted to NFL edge speed, but he wins when he gets his hands inside oppoents and can steer them out of plays. Appears equally proficient run and pass blocking and with continued refinement might not have any glaring weaknesses.

NFL comparison: Zack Martin

Draft range: Top 25 pick

14. Iowa OL Brandon Scherff

6-5, 319

Country-strong, powerful run blocker who seeks to maul and wrestle opponents with his great lower-body drive. Scherff played tackle in college and could play either tackle or guard in the NFL, giving him some flexibility. Can power clean a truck (well, not literally) and uses that base strength well, even though his 23 reps on the bench press put him in the lower range of offensive tackles who lifted at the combine. Pass blocking is not his forte, but it might not be a weakness either if he learns to finish better and shift and adjust to speed better. Like most linemen bred in Kirk Ferentz's program, Scherff has a high floor, is well-conditioned and should find a home for many years in the NFL even if his upside is not sky-high.

NFL comparison: Bryan Bulaga

Draft range: Top 15 pick

15. Alabama S Landon Collins

6-0, 228

Athletic thumper with an edge whose best work has been done closer to the line of scrimmage. Collins might have lost some speed — at least, it appears that way on tape — from 2013 to last season and dropped several interceptions, making scouts nervous if he'll ever be a great coverage player. He's tough against the run and can track down running backs and tight ends well. Has great diagnostic skills and should be an ideal eighth man in the box as a tone-setting hitter. Can move well in space, more so with his instincts than his raw foot speed. Might be exposed if he's asked to match up with receivers, even slower-footed ones, in man coverage. There's a big debate in scouting communities about whether Collins can be a great back-half defender (like several other bigger safeties who have come out recently) and whether he's been Nick Saban-ized, with several Bama DBs maxing out in college and seldom becoming great NFL players.

NFL comparison: Reshad Jones and Da'Norris Searcy, who are better players than they are given credit for being but are not superstars

Draft range: Top 20 pick

16. Michigan State CB Trae Waynes
6-0, 186

Blazing straight-line speed and great height for a corner. Great man corner who can flip his hips and run with even the fastest vertical receivers and can make up ground on the rare occasion he lets his man get behind him. Waynes can struggle with short-area quickness, lets too many passes get caught in front of him near the line of scrimmage and can get grabby, which is a concern with new NFL rules with illegal contact. Former Spartans defensive coordinator Pat Narduzzi trusted Wayne to play on an island and frequently matched him up with the opponent's best receiver. Might not be best used in a predominently zone-based scheme.

NFL comparison: Faster, slightly bigger Tramon Williams

Draft range: Top 15 pick

17. Stanford OT Andrus Peat
6-7, 313

Tall, long-winged, lock-out left or right tackle with light feet. Peat can anchor and drive block and has no massive holes in his game. He will grab and reach and occasionally get off balance and display weakness when having to adjust to stunts, twists and blitzes. Was outplayed overall on the handful of snaps he went head up against USC's Leonard Williams. In addition, faster rushers can give him problems when they're screaming off the edge. Overall, Peat is a very good-looking prospect with the height, reach, intelligence and fierce competitiveness to be an upper-echelon tackle in time with some technique refinement.

NFL comparison: Somewhere between Anthony Costanzo and (a healthy) Jake Long

Draft range: Top 25 pick

18. Washington LB-RB-S Shaq Thompson
6-1, 228

Is he a linebacker? A running back? A safety? After a failed flirtation with baseball, Thompson became the most diverse and perhaps dangerous playmaker in college football last season. He averaged nearly eight yards per carry as a running back and had a 41-yard reception; Thompson also had a pick-six, three fumble-return touchdowns, three forced fumbles and 81 tackles. Undersized but electric, Thompson can track down plays from behind, has a knack for sniffing out screens and misdirection and can sink and drop into coverage. But again, what is he? Too small to play anything but a 4-3 weakside or perhaps a 3-4 inside position defensively, and likely a step slow as a big safety — that's the issue. For a creative team seeking an impact defender without ideal measurables and willing to work around his flaws, Thompson could succeed. But that team must have a plan for him and likely be patient, maybe using him in doses on offense or special teams while he develops.

NFL comparison: A combination of Daryl Washington, Deone Bucannon and Rashad Jennings (yes, we're sober)

Draft range: First round, we think

19. Texas DT Malcom Brown

6-2, 319

Brown made huge strides and burst onto the scene as a junior, displaying good penetration skills, quickness off the snap and great recognition to find the ball. In fact, that might be his most notable instinct on tape: Brown is exceptional at locating the ball, even when having to fight through the trash. He doesn't play as big as his frame would suggest and can't be more than a gap-shooting nose tackle in a slanting scheme. Brown looks best as a three-, four- or a five-technique, and that versatility should help him appeal to most schemes. Will he ever be consistently dominant, be able to fight through double teams and be a great run defender? That's hard to forecast.

NFL comparison: Marcell Dareus

Draft range: First round

20. Oregon DE-DT Arik Armstead
6-7, 292

Flirtatious talent whose football likely is in front of him. Armstead has the traits of a dominant player and will win individual battles but also leaves observers wanting more. In 3-4 years, Armstead could be the best five-technique in the league; or he could be a rotational player who rarely dents the stat sheet. With better ball recognition and a better pass-rush arsenal, Armstead's rare measurables could allow him to be a double-team candidate. But he's not a complete player right now. Some team is going to be gambling on greatness when they turn in the draft card with his name on it.

NFL comparison: Jason Hatcher

Draft range: First round
