I know this is obvious, but- just need players. size is only part of the equation. earl thomas is 5' 10". the SB MVP was a 220 lb. 7th round OLB....
Solid point. They've got a helluva defense. They're deep, too. Michael Bennett earned himself some money last night. It seems like they may have thought about getting bigger DB's intentionally, though. Browner, Chancellor, Sherman, etc. Those guys are hard to come by.
Schneider absolutely went after bigger corners deliberately. And lucked out a little bit too, really. It's not like Sherman was a dead nuts, sure-fire lock as a CB when drafted. He was a WR convert at Stanford with questions about his ability to stay on the outside (or even on D, according to some services at the time).
