Check back here for position-by-position breakdowns of the Temple depth chart leading up to the start of the 2018 season.

We've also previewed the quarterbacks, defensive linemen, running backswide receivers and tight endsdefensive backs, offensive line and special teams. Here are the Owls' main linebackers:

Shaun Bradley

6-1, 225, Jr., Mount Holly

Bradley ended with a team-leading 85 tackles and added 10 tackles for loss while playing in the middle of the 4-3 defense. He isn't as big as many middle linebackers, but his strength is his speed. Bradley can cover even running backs out of the backfield.

Early last year, Bradley acknowledged that he was adjusting to playing the position since he mainly was on special teams as a freshman.

He is such a good athlete that Bradley had two carries last year as a running back. A graduate of Rancocas Valley High, Bradley is a true leader whose confidence is infectious.

William Kwenkeu

6-1, 230, Jr., Waldorf, Md.

Kwenkeu can play inside or outside and is one of the Owls' hardest hitters. He made just one start last season, in the Owls' 28-3 victory over FIU in the Bad Boy Mowers Gasparilla Bowl. It was Kwenkeu's best game, as he contributed six tackles and two assists a day after becoming a U.S. citizen.

Despite the one start, he played extensively and finished with 34 tackles and four tackles for loss.

Sam Franklin

6-3, 210, Jr., Crystal River, Fla.

He started eight games and, like Bradley, has tremendous speed. Franklin had 59 tackles and four sacks and also had a big bowl game with seven tackles. He can also be a key performer on special teams. He might be the best coverage linebacker and even can be moved to strong safety in some packages.

Isaiah Graham-Mobley

6-2, 220, R-So., King of Prussia

Last season, he appeared in 11 games and made two starts. The Upper Merion grad will push for time on the outside and also be key special-teams contributor.

Todd Jones

6-0, 220, Gr., Philadelphia

A former walk-on who eventually earned a scholarship, Jones got his chance when injuries hit the unit last year. The St. Joseph's Prep graduate had 32 tackles in 10 games, making three starts. He is among the team's hardest workers.

Chapelle Russell

6-1, 225, R-Jr., Lakewood, N.J.

Russell was the Owls' leading tackler through nine games, then suffered his second career torn ACL before the 10th contest. He might not be ready for the Sept. 1 opener against Villanova, but whenever he returns, Russell is expected to be a main contributor. Like Bradley and Franklin, his best asset is his speed, and he is especially adept at tracking down ball carriers from the back side. He is among the most respected players on the team for his dedication in coming back from the two knee injuries.

Audley Isaacs

6-1, 227, R-Fr., Philadelphia

A product of Valley Forge Military Academy, Isaacs has made an impression during training camp. He is considered one of the leaders of his recruiting class.

L.J. Holder

6-2, 215, R-Fr., Manalapan, N.J.

Holder entered Temple as a tight end, but with ample depth at that position, he moved to linebacker during spring practice and made great progress. Like many of Temple's linebackers, he has good speed.
