It stinks when late round players you could have selected are actually decent, but I don't think Bane would really make our break our franchise. We don't have any proof that we would have actually taken Bane either. Yes, he was the choice at #30, but he wasn't necessarily our choice. He would also not be playing half the game or be getting nearly the usage in Boston.
Besides, I just choose to look at it as the compensation we gave up for the Hayward TPE. We gave up two of our future 2nds to CHA, but we received two (better) 2nds in return for the #30 pick. We are still all square as far as our future picks go.
