That's not a fair way to put it; if RG3 is a franchise quarterback, the deal will work out for them. I'm not a big fan of the deal just because I'm not as certain of Griffin's success as others are, but if he becomes a top 10 QB, it's a fair deal.
I would add that if tannehill or any other qb from this becomes a franchise qb, or if next year's pick is good enough to get us a franchise QB, it's not worth it. I think that if everything pans out and griffen leads us on multiple playoff runs then it's a great deal, but he's a big 12 qb from a spread system, I have my doubts; I would have felt far better if this haul got us luck
