I'd love to have Bosh here. Fantastic player.
I don't think Miami will trade Bosh though. Riley doesn't strike me as the "blow it up" type. He hates losing, hates rebuilding. No patience for it. Gave up coaching last time Miami had to go through one. And that last rebuilding period was forced not chosen. I can't see a guy like Riley giving up a big man as talented as Chris Bosh to purposefully lose more games so he can have multiple seasons of horrific losses in order to gain draft picks.
Chris Bosh gives him a foundation to build a team around. That is something valuable and to be cherished which is how I expect Riley to view Bosh. So long as Bosh is there, Miami has hope to build a better team. They will always attract FAs. Always have, always will. Just need to give guys a reason to come there. Bosh is a huge part of that reason.
