Why? Saric is an expiring who (in my opinion) is unlikely to stick around, and the Suns get a first round pick for no long-term salary and a first round pick.
He is a starter, no? Their leading rebounder and they are third in the Pacific Division. That means they may want to add pieces not give up their starter for a pile of crap and a pick. They are one spot out of the playoffs as it stands right now.
This is NOT NBA LIVE or NBA2K.
I think a more realistic deal would be with a team out of contention wanting to shed cap space. I think CLE is a good example of a team that might be intrigued by some picks.
