Hey I thought this was a really interesting and clever trade. I'm not thrilled about losing JET but I really like Watson. I know he has some decision making problems but I think he's a very good backup PG. I also think at 28 he's settled in to the idea of a bench role. He's never started consistently (around 17% of his games).
Humphries is an obvious upgrade over Bass in everything but mid-range shooting. It's not like we lack that right now.
I'd make this trade for sure. I'd also accept a Watson/Blatche swap. I think to get a capable big man we should offer Lee or Terry.
