I don't see how the new coaching staff at Arizona could know Davis much better than our coaches do. They came in after the season and only had tape to watch, just like we did. I've never heard anything about Davis being Lazy until this offseason once the Cards said they were going to let him test free agency.
Just because they let him go into free agency doesn't mean they didn't want him back. They just weren't going to pay franchise money for the guy.
Heck, that's no different than Cincy did with Steinbach and I never saw anyone questioning Stenbach's work ethic. It's no different that San Diego did with Dielman, and they even resigned Dielman... I never saw anyone questioning Dielman's work ethic.
I suppose since Arizona didn't resign him before FA and since he is so big that people just assumed the guy was lazy and that's why he saw the light of day in free agency.
I think it's a simple case of Davis not being able to play LT very good and them thinking that the really big money should go to LT along the OL. That and a new coaching staff trying to shake things up and bring in a new mentality on the team. Plus, if you look at Pittsburgh and where they learned to run a team... the Steelers never sunk big money into the OL. Heck, they didn't spend big money on much of anything, for that matter. Who knows if Bill Bidwell didn't hire Wisenhunt because he learned to run an organization without having a lot of big ticket players... like Pitt.
