SF LB situation

Based on his poor performance (not fantasywise) last week, is there any chance that Bellore be benched and Wilhoite claims everydown role? Or is this the situation we better avoid? I picked up Wilhoite last week and wonder it is good idea to drop him for Bellore or more proven guy such as Ellerbe.

Ellerbe has his own shaky situation since the Saints are mixing up their whole defensive lineup and Craig Robinson has become a clear staff favorite. I just dropped Wilhoite for Bellore, but I didn't watch Sunday's game and didn't realize that he performed sub-par
