I think, Roy doesn't work hard enough to improve, which was noted by even Micky Spagnola, who really never goes out on the limb to critisize current cowboys players.
And, I never said this before, but it always bothered me, when they drafted Roy Williams, that he said, when he isn't playing, he doesn't watch film or study game etc. His hobby in off season is just to watch movies.
Now, during 1st 2-3 his play was not bad to be a concern. But you can see more and more, when you're first priority is not Football or at least maybe 2nd priority, I don't see how you can improve as player?
He also completely lost his confidence in coverage and that shows up. 3Rd, he has this confrontational style with Media, which doesn't help him and is very sensitive to critisizm.
I think Roy has worn out his welcome and probably needs a change of teams to get better. Probably by next year, he will be gone, i.e. in 2009. Unless he really works at his craft this year and shows improvement in 2008.
