You are comparing the Starting #1 WR for the TB Bucs to the 3rd option at WR and 4th option behind TE Witten for the Cowboys who had their back-up QB. On top of that Dez was injured and missed games. Yet, in spite of less time on the field and targets Dez still put up great numbers.
M.Williams might be a solid Wr but Dez has WAY WAY WAY more potential. I hate the cowboys but Dez has the Irvin quality that Williams doesn't.
