Harvin played all 16 games last year and I believe has only missed 3 games in his 3 yr career (Dez has missed 5 in 2 yrs). Harvin also played with some of the worst QB's in the league last year, had no help at the WR position and still put up very good numbers.
I'm not saying I'd trade Dez for Harvin, but it certainly isn't as laughable as you all are making it out to be.
Surprising stats! I would do everything I could to get Harvin in a Cowboys uniform.
