Whitner did play LB. By bringing him up I'm not questioning his ability to play the position, I am questioning the decision to play a 4-2-5 formation when one of your starting LBs is 6'0" 215 and your nickel CB is 5'8" 177.
They are "playing small" just by taking a LB off the field, but when the players in these positions are even smaller than average its an additional concern (for me anyway).
I think Cordy will do a great job, especially covering guys like Sean Riley, in the slot. He plays bigger than his size when he comes up to defend the run in the open field. But, if he's going to be closer to the line of scrimmage, he could be easily pushed around at the line on run plays.
Whitner being a former Safety should be one of our better cover LBs. Against a quick passing team like ourselves, it should be very effective. However, if we trot out the 4-2-5 defense, especially at our current size, the opposing offense can run the ball at will and keep us from making substitutions. I saw it with the Bills.
Again, I am happy to be wrong, and trust Babers, but I am definitely concerned. In the future, when we have tall and rangy LBs that are 6'4" 227 like Richards it could be different. Having safeties like Cam Jonas 6'1" 209 is going to help. CBs like Trill at 6'2" 202 is amazing no matter what defense you run. Maybe they've always wanted to run this defense, it did seem like they were recruiting for the transition, but is this season going to be a painful first year? And, can Babers withstand another year of not winning because of his defense?
