I don't think any player is worth what the Cowboys gave up for Roy Williams.
Having said that, I think the Jury is out on how well he can play in Dallas. Tow things are working against him: (1) his lack of timig with Romo and (2) injuries.
First - on his timing - I can't blame him for still not having it with Romo because all the WRs look lost this year. The whole passing game is out of synk, so I have to put that on coaching beofre I put it on any player.
Second - on injuries - Roy Williams has been injured since he got here. He had the toe last year, on top of coming in without the benefit of campp to prepare with the QB. And this season, he's had back-to-back injuries since day one. Frst it was the shoulder injury he suffered at the end of camp/preseason. And now he has the ribs.
Early on there were some balls he dropped that he normally does not drop; that's the shoulder injury right there. Yet we hear how he's still open much of the time and Romo can't feed him the ball. And now he won't get hte chance because of te strained ribs. Again, can't put that on him.
