I've been saying for years now that Iguodala would be the perfect SG beside Rondo and Green. I think then we'd only be a Tyson Chandler type C away from being a contender. I'd gladly take Thompson as well, though GS would be foolish to trade either.
I believe the Warriors already have a ton of money invested in Curry, Iguodala, David Lee and Andrew Bogut.
So, are they going to have enough money to resign Thompson?
If they do, wouldn't someone have to be the odd man out?
Curry/Iggy/Bogut don't make THAT much over these last 3 years, Lee is the only one with big money and he's expiring next year (plus don't forget, Bogut and Iggy have declining salaries). I wouldn't say they have a ton of money invested. It's 50 million for their 4 best players, which isn't so bad for a contender. Not too long ago, we had way more than that invested in only 3 players.
Of course, they can sign Thompson no matter what, but I'm pretty sure they can fit him in without going over the tax. If they were really forced to make someone the odd man out, I think they'd rather dump one of the older guys (Lee or Bogut) than screw up their awesome perimeter.
