I don't see the two situations as similar. Not only did most ppl here think we gave too much, he still had 4 years on his rookie deal, had superior physical ability (obviously not even close in the heart category), and the team was going a different direction (Murray) regardless.
I'm not promoting any agenda. In fact, you are the one who started this highly speculative exchange. Personally, if Tua performs like a top QB this year, I think it would be quite silly to trade him away and roll the dice again. That has nothing to do with what I believe other teams would be willing to give for him today.
