Let's start by saying that Thomas and Nocioni are anything but "pretty damn good". Thomas still doesn't have a wee-bit of a basketball IQ, Nocioni is over-rated and doesn't deserve half of that contract we gave him, and Deng may not even be with us next year, and the same goes for BG as both are FA's.
Now on to your trade scenarios. Here's my thoughts on your prosposals, respectively:
Could happen. Although, he's injury prone and who knows how good he'll be without the 2nd best PG in the game.
Won't happen. Yeah, he knows how to play, with a real friggin' PG. And, it won't take the #1 pick for him. It'll take TT, sign and trade Gordon, and Gooden.
Ehh, on this one. Nene and Martin don't do much for me.
Won't happen, unless that is we give up this #1, next year's #1, Gordon, TT, Gooden, and Hinrich. Not to mention probably Hughes and Gray. AKA, our whole team.
Slight chance. Bosh refuses to get stronger which angers TOR management. It'd probably cost us our #1 next year, Gordon, and Gooden. And maybe TT.
