A fumbling problem is to be expect from a rookie running back. The problem is the Titans are going to be relying on Bishop Sankey to be their No.1 running back alongside an injury-prone Shonn Greene.
Sankey has to correct his troubles with holding on to the ball. This offense has a small margin for error, and turnovers will keep this unit buried in mediocrity for another season. He's going to see a lot of touches, and with that have a lot of opportunities to stall drives through turnovers.
This concern wouldn't be nearly as high if Sankey was backing up a veteran that was going to be the primary ball-carrier.
The Titans had five ugly turnovers in their 31-24 loss to the Saints, and Sankey contributed to that number when he fumbled an exchange from Zach Mettenberger.
Ken Whisenhunt commented on this issue, per Paul Kuharsky of ESPN.com:
Whisenhunt realized he's dealing with a rookie who is going to make some early mistakes. Hopefully it won't cost the Titans a couple vital wins in a division that will be a close race. The Colts are the favorites, but the gap isn't huge.
The expected rookie growing pains for Sankey elevates the importance of Greene to be healthy for Week 1.
This is exactly why the preseason is so beneficial for rookies. Sankey's talents will eventually outweigh this turnover concern. Two more preseason games worth of reps will will have him ready for the regular season.
