Sherman is a west coast offense guy. The WCO is rather complicated and takes years to learn and is, IMO, producing diminishing returns. To me, a good fit is somebody who will come in, and put together an offense and defense that will make the most of the talent in place. I know Sherman won games, but he inherited a team with the best QB in the NFL and a deeply established WCO system and he didn't do anything special. Yes, he won and made the playoffs in the NFC Norris, but in the playoffs they got handled. He was a lousy GM as well. To me, he is a poor man's George Siefert, and we saw how he handled starting from scratch in Carolina. AVOID this guy.
I would rather have a lot of other coaches. Martz would be a fit for the talent in place and would do wonders for Losman, Evans and Parrish, IMO. I'd even rather have coach HAY-ZLITT. God, I'd even rather have a re-tread like Dick Jauron.
