So as I understand it, you wouldn't take a run on a single, first round pick, because that's "random," but you would take the chance on possibly giving up two picks on a franchised QB on a rookie contract, because teams would so willingly allow you to do so? Why not just rub a genie's lamp and wish for a franchise QB?
Talk about random.
If said team would let their "franchised QB" (actually, non-exclusive franchise player) go, the Cowboys would be on the hook for TWO first round picks, and this you feel is a perfectly sound philosophy and not "the dumbest thing you've ever heard?"
Did you not see trades like Herschel, Roy Williams, Joey Galloway, RG3, Ricky Williams, etc. blow up in their teams (Cowboys twice, for the love of Pete) face?
Why on earth, if their QB is indeed a franchise player, would a team let them go, knowing how hard it is to find a real franchise QB? Could anyone ever see the Colts letting Luck go or the Seahawks let Wilson go (is this the unlikely scenario you're personally hoping for?)?
And, if any team DID let their franchise QB go, would not you feel like the Cowboys got hoodwinked into buying fools gold? Could anyone imagine the Cowboys blowing two first round picks on QBs like Geno, Austin Davis, Hoyer, etc.? TWO first round picks.
And Vets? Please. How many times, in the last decade, has a vet gone on to other teams to be anything special? Alex Smith? Matt Schaub? Fitzpatrick? Cutler?
The only one that comes to mind is Brees, and I'd say his scenario is much rarer than actually drafting one.
So, the idea of taking a run on a franchised QB or a washed up/journeyman vet seems like more of a sure thing than drafting and developing a high draft pick?
Gotcha.
