The bosh trade make a little bit of sense, but the compensation for raptors can't be Tony Parker...
The window I see, is something like : Jefferson and rights to Splitter to Toronto
Bosh (and Weems) to S.A.
Bosh want to be in a contender team, better if from Texas, and SA is ok with both these requests, and will take the maximum money with a sign and trade.
He's in good relationship with Raptors and will make everything for maximize the thinghs they could take for him.
For S.A. that could be a good trade, considering they take a proven and young big next to Tim and that could let the chance to spend the MLE on a good wing player replacing RJ.
For Toronto is good because RJ is made for playing in un up tempo system, like the one played with Calderon, Splitter is an international of very good level and with a great upside going in an international organization like the Raptors that need a Center...so he will have a lot of playing time (like he wants) from the beginning.
Looks like everyone couild be happy, at the end...
