1. Myles Garrett, DE, Texas A&M, Jr, 6-5, 262, 4.74
He had eight tackles over his first three games, but Garrett has proven much more disruptive than these statistics suggest, registering 2.5 tackles for loss and two sacks in the Aggies' SEC opener September 17 against Auburn. The former consensus five-star recruit has been a terror since stepping onto the field for the Aggies, answering his breakout freshman season (53 tackles, including 14 for loss and 11 sacks) with an even better one last year (59-19.5-12.5). Boasting a prototypical blend of explosiveness, flexibility and length off the corner, Garrett has the look of a future Pro Bowl regular.
3. Jonathan Allen, DL, Alabama, Sr, 6-3, 292, 4.85
With 12 sacks last season, Allen was the most disruptive of Alabama's dominant defensive line a season ago. In fact, one of the reasons why A'Shawn Robinson and Jarran Reedsurprisingly slipped into the second round in the 2016 draft is that talent evaluators realized the best prospect of the bunch -- Allen -- had returned to school. Allen was dominant in wins over talented Southern Cal and Mississippi squads, registering two sacks (among his four tackles) and two pass breakups against the Trojans and pulling a Chad Kelly fumble out of the air and racing 75 yards for a touchdown against the Rebels. Allen, who reminds me a little of Seahawks Pro Bowler Michael Bennett, is position versatile with surprisingly light feet and dynamite sticks for hands.
4. Jabrill Peppers, SS/OLB, Michigan, rSoph, 6-0, 208, 4.48
Michigan is loaded with NFL prospects and Peppers, just a redshirt sophomore, is the best of the bunch. Peppers is the latest in a new line of defensive 'erasers' capable of lining up at safety, linebacker or cornerback similar in style to recent first-round picks Deone Bucannon, Damarious Randall and Shaq Thompson. Scouts likely won't take much from early season tuneups against Hawaii, Central Florida and Colorado except for the unique versatility that he's demonstrated, accomplishing the rather unique feat of leading the team in tackles (28, including 9.5 for loss) and all-purpose yards (278), including a 54-yard punt return for a touchdown last week against the Buffaloes.
5. Malik McDowell, DT, Michigan State, Jr, 6-5, 282, 4.92
With all due respect to Notre Dame quarterback DeShone Kizer (No. 9), McDowell was the best player on the field during the latest clash of these rival programs on Sept. 17. Lined up inside and out, McDowell consistently generated pressure against an offensive line full of NFL prospects, winning with a remarkable combination of length, power and agility to record four tackles, including one for loss, in the Spartans' 36-28 win.
11. Teez Tabor, CB, Florida, Jr, 6-0, 199, 4.52
Until this summer, Tabor's first name was Jalen, though his new name may provide a more accurate description of his game. Tabor teases with an exciting combination of size, fluidity and speed, standing out in coverage and as a gunner on special teams the past two years. Tabor was more consistent in coverage last year than former teammate Vernon Hargreaves III, the No. 11 overall pick this spring by Tampa Bay. Tabor was suspended (reportedly for a fight with a teammate) for Florida's season-opener but returned in dramatic fashion in Week 2 against Kentucky, showing terrific recognition to read a wide receiver screen and stepping in front of the intended target to steal his first interception of the season.
12. Marlon Humphrey, CB, Alabama, rSoph, 6-1, 198, 4.53
One of the best looking prospects I've seen this season is Humphrey, who wowed last year in his debut season after redshirting in 2014. The son of former Alabama (and NFL) standout Bobby Humphrey, Marlon looks like a chip off the old Tide with his easy change of direction and acceleration. He's well-built for a young player at a solid 6-foot-1 and 198 pounds and is an aggressive tackler, including in run support.
13. Reuben Foster, ILB, Alabama, Sr, 6-1, 240, 4.72
Reggie Ragland was the SEC Defensive Player of the Year last season but Foster could earn a higher draft selection this spring. Foster is a more explosive athlete, showing ridiculous closing speed and an utter disregard for his own safety or that of his opponents. Foster might be the most intimidating hitter in all of college football, and he possesses the fluidity and speed to cover.
19. Lowell Lotulelei, DT, Utah, Jr, 6-2, 310, 5.28
Today's NFL may feature the pass, but interior defensive linemen remain highly valued on draft day for their ability to eat up blocks and collapse running lanes. Few are better at this than Lotulelei, who possesses a similar combination of size and brute strength as his older brother Star, a former Morris Trophy Award winner for the Utes and current standout for the Carolina Panthers.
