First off let me say that I coach football. I'm not naive about position switches and understand that there are physical skill set differences and assignment changes. HOWEVER, I do find it hard to believe that after one or two years experience you can't just get the seven best people on the force unit out there. Vince Williams is a tackling machine. He has good enough speed, pretty good instincts and a mean attitude. I find it hard to believe they couldn't have coached him up in an entire winter to prepare him for both positions. Pretty hard to send him back to the bench when Shazier is healthy. Shazier makes more spectacular plays but frankly overruns a lot of plays. Vince is a steadier player. And if it is Vince inside and Shazier as a pass rusher or cover Olb that is fine too.
