Casey Hampton, I don't know why everyone thinks in a 4-3 he'd be useless, he's a hold the point run plugger, with another guy on the line, thats less Double teams, he's athletic enough to get into the backfield.
Brett Keisel put up great stats in a 3-4 as a part time Passrusher from the RDE spot. I think he could be an Aaron Schobel like pass rusher, not the great Physical aspect, but the non-stop motor.
Which is likely what it will look at during times Woodley comes up from LB to put his hand down...
At which Timmons/Harrison will be WLB, Foote will be MLB and Farrior SLB.
