The Heat should have signed Bosh instead of Bosh. That would have been insane.
Yes, but could they have signed Bosh for less money than they signed Bosh for? That would have been a neat trick.
I don't know how well it would've worked with Bosh, at least not like it has with Bosh. Whether they made the right decision in signing Bosh over Bosh, time will tell. Regardless, both Bosh and Bosh are soft tough-guy tools.
