McFadden & Julio
MJD > DMC - McFadden can't stay healthy, but MJD is due for a fall - he's getting older and has a lot of wear and tear over the past couple of seasons. MCFadden is also a couple of years younger, and therefore, should be a better long-term player.
Julio > Dez - Bryant has a ton of potential, but is too immature to realize it, and as long as Jason Garrett is the HC in Dallas, he won't be forced to step up. Julio has as much, if not more talent, more maturity, and plays on a more consistant team than Dez.
I think it's pretty clear, but I'd love to hear an argument for the other side...
