Ranking: The Rialto (Calif.) Wilmer Carter prospect was rated as a four-star in the 2013 class but was outside the Rivals250. Clark was No. 39 in the California state rankings.

Recruiting: UCLA and Washington were the two finalists for Clark, who took an unofficial visit to Seattle in July and decided he wanted to stay closer to home. The Huskies were a serious contender and he liked his visit, but location played a big factor.

Overview: Clark is second on the Bruins with 30 tackles and he has 3.5 tackles for loss. No other UCLA defensive lineman is even close in the number of tackles so far this season. He finished with eight stops (two for loss) in the loss to Arizona State this past weekend.

Farrell's Take: Clark was an athletic and quick defensive tackle out of high school with a good frame to build on. He was very powerful despite checking in at around 275 pounds and he has filled out that frame very well in college. He's athletic, he can chase plays down and he's a load to handle in the middle when run blocking. He was also and remains a sure tackler, something that is overlooked a bit at his position.

Ranking: Collins was a three-star prospect out of Kansas City (Mo.) Center in the 2013 class and rated as the No. 30 defensive tackle.

Recruiting: Collins, also a standout high school wrestler, said leading up to his decision that Nebraska, Missouri, Kansas and Iowa were the frontrunners but admitted he was mainly focused on the Huskers and in-state Tigers. Nebraska landed his pledge in early January.

Overview: Collins had an outstanding game even though Illinois scored two fourth-quarter touchdowns to beat Nebraska, 14-13. He finished with nine tackles (three for loss) including 1.5 sacks. Collins has 16 tackles and three QB hurries on the season.

Farrell's Take: Collins is very good at penetrating because of his quickness off the snap - that was his strength in high school as well. Collins was a very active tackler coming out of high school and was always in the opponent's backfield but questions about how stout he could be in the middle against the run held him back from a fourth star. He will have to answer those questions at the NFL level as well, but he's the best pass rusher on this list.

Ranking: The Houston, Miss., recruit was rated as a five-star and the second-best strong-side defensive end in the 2013 class. Jones was No. 20 overall and first in the Mississippi state rankings.

Recruiting: Two days after working out at the Mississippi State camp leading up to his senior season, Jones committed to the Bulldogs. Considered a sleeper at the time, he later moved to five-star status. Jones showed significant interest in Ole Miss close to Signing Day, but decided to stick with Mississippi State in the end.

Overview: Jones had five tackles (one for loss) in a 30-17 defeat to Texas A&M on Saturday. For the season, he has totaled 23 tackles (two for loss) including 0.5 sacks. Linebacker Richie Brown leads the team with 50 stops.

Farrell's Take: Jones was a late five-star discovery for us, and most in the industry, as he was simply dominant at the Alabama-Mississippi All-Star Game. He was similarly impressive in the Under Armour All America Game and, like many players from Mississippi, was under-scouted and under-recruited. But in the end we got the ranking correct. We didn't see him moving inside like he did, mainly because he's so tall and long, but that length allows him to make so many plays around and behind the line of scrimmage and he plays with excellent leverage for a tall tackle. His athleticism could send him soaring up the charts after the NFL Combine and his Pro Day.
