I don't know why everybody thinks it's unlikely that Golden State takes contracts..I'd actually be surprised if they didn't jump at the first decent offer..
Bonner + Mason WILL do it IMO, unless another team overspends..Jackson's contract is bad, he's old, and he doesn't want to be in Golden State anymore..they have no reason not to trade him..he isn't a good enough player that they'll hold out for a good offer, he's not an all-star or anything..they already have players for the future that they're trying to build around..cap space is good enough for them IMO..
It's up to whether or not the front office is willing to do it..bad contract, as Bruno said, he'll be getting paid 10 mil at age 35, which is horrible..then there's the possible chemistry and stylistic issues with acquiring Jackson..
If the front office wants it, I think we can easily pull off a trade..I don't think they'll want it though..maybe explore it again at the deadline..
