Strong and weak: Arkansas Razorbacks

Every year, players come and go in college football. With that teams can either grow or take steps back because of turnover.

It's time to check out Arkansas' strongest position and weakest position heading into the 2013 season:

Strongest position: Defensive line

New coach Bret Bielema wants a powerful team and he'll have a pretty good unit to work with along the defensive line. Three starters are back in tackle Byran Jones and ends Chris Smith and Trey Flowers. They are all talented, they are all veterans and they all registered more than 50 tackles last year. Flowers and Smith might actually be one of the most underrated defensive end duos in the SEC, as they combined for 26 tackles for loss and 15.5 sacks in 2012. This was the only duo to rank in the top five of the SEC in tackles for loss per game and in the top eight in sacks per game. Jones added five tackles for loss and 1.5 sacks. You also can't forget about Robert Thomas. He played in 12 games last year, registering 18 tackles, five tackles for loss, and 2.5 sacks. The Razorbacks will have a strong starting line and should be able to generate good pressure against opposing passing games, while still being able to clog holes against the run. The biggest thing this line needs is consistency

Weakest position: Running back

Inexperience is a major issue at this position. Jonathan Williams returns as the leading rusher for this team after rushing for 231 yards on 45 carries last season. He had a good spring and could be the workhorse back that Bielema needs for his offense, but the sophomore has limited experience. Sophomore Nate Holmes will have a chance to contribute, but only carried the ball three times last year, while redshirt sophomore Kody Walker has played in five career games, but has missed substantial time because of injuries. You could also see fullbacks Kiero Small and Morgan Linton get some carries with the style of offense Bielema likes to run. Help is definitely on the way with freshman Alex Collins coming in, but he'll have to grow up in a hurry during fall camp.
