Hightower still starting RB
The Arizona Cardinals still have running back Tim Hightower at the top of their depth chart.
There has been some talk that running back Chris Wells would take over the lead role for Hightower.
Both players struggled with holding onto the ball at times last year, although it was more understandable from the rookie Wells.
Head coach Ken Whisenhunt said both Wells and Hightower are good players and there is a long season ahead of them.
Hightower is the more effective player on passing downs while Wells is the bigger, more punishing back.
