I think people prefer Bosh because of his complete statistics. I prefer Amare. I really do. Amare can explode. I know he can't explode the way he did pre-microfracture, but he still has it in him. I would prefer his explosion to the finessed completeness of Bosh. I like the idea of raining outside shots with Gallo, TD, and whoever else, letting Amare explode down low, and letting TD, Chandler, and Ellis/Parker go hard to the rack. Strategically, I prefer that. That's hard to contain.
Lee is a poor man's Bosh. And, I brought this up previously, and guys like TMS pointed out the flaw in a Lee/Amare frontcourt. The flaw being I can't think of a frontcourt that was as bad as that would be defensively that won an NBA championship. The appeal is if you throw Lee into the mix you have a big has some range, efficiency, some driving ability, some passing ability, and is just an x-factor in the mix. You'd get two unique offensive skillsets that would work together. In theory, Lee and Amare could run the pick-and-roll TOGETHER.
So, if you keep Lee instead of trading him for Ellis/Parker, and replace either with Mike Miller, I think that team would be pretty dynamic. TD/Miller/Gallo/Amare/Lee with Chandler and Walker the key contributors off the bench. I think that's the way I'd go.
