The final area of concern should be Pitt's running game.
They will return freshman James Conner, who led the Panthers in rushing yards with almost 800 (and eight rushing touchdowns). However, head coach Paul Chryst also was putting Conner on the other side of the ball at defensive end, which we saw glimpses of in Conner's breakout bowl game.
Conner, listed at 6-foot-2, 230 pounds, clearly is a North-South style of runner. He also made plays on the defensive side of the field throughout the season for the Panthers.
In my opinon, Chryst should keep him at running back. The Panthers could use incoming freshman Chris James for the outside running plays and let Conner bruise up the middle. When you have something good, you shouldn't change it. Conner changed his number to 24 for this season, which could lead one to believe that the Panthers permanently will use him as a running back.
