Early in the season opposing defenses were bracketting Whitten a lot and Owens benefitted greatly from this. So then teams started bracketting Owens and Whitten started to get hot.
Philly did to Dallas exactly what they did to us, only better, and they did not over respect Ownes.
I can't see Carolina or Washington having the personnel to play Dallas like Philly did, so if Dallas is to lose their final two games, it won't be because these teams emulated the Philly game plan.
Consistent pressure on Romo seems to be part of the equation in stopping the Dallas offense. (Which anybody could say about any of the other 31 teams.)
