As mentioned above, Norv Turner might actually be a consideration. He was Casserly's choice for the Redskins back in '94 and he remained after Casserly left so Casserly may actually still consider him a good choice since he never fired him.
Not seeing a lot from Casserly in terms of drafting a QB. David Carr and Heath Shuler are his two early picks at the position and not a whole lot else. He did acquire Brad Johnson which is a point in his favor but overall, I'm seeing a lot of QB choices that were failures.
But, we're not actually talking about Casserly as the GM so I don't know if he's going to be doing GM duties once he hires one. It may be left primarily up to the GM to select a HC/QB.
