[Defensewins]

Nothing wrong with bringing in VY for cheap to compete for a roster spot. The key is he has to come cheap. Both in cost to get him (none) and his contract has to be cheap.
He should be viewed as a backup who will compete with Beck and someone else (maybe Grossman) for the starting job.
It would be interesting to see VY run the naked bootlegs that MS likes because the defenses will have to be extra careful with VY's athleticism to make things happen on the edge. Especially if we can get our running game cranked up and if VY can get some accuracy and consistency going in the passing game. It would be tough to defend all of it. Our new WR's size (Hankerson) and speed (Aldrick Robinson) adds to this equation.
I am not saying this will definitely happen, I am just saying there is nothing to lose in trying it out.
