Why would OKC do that trade? OKC doesn't need a blackhole on offense and somehow who'd ruin their chemistry. Perkins may be useless on offense but he provides solid defense and the terminator role that Cousins will never provide.
You need team players like Perkins and Collison, players that provide balance for the team.
I really think that the situation in SAC is bad for him. With a better team and better coaches, he might figure it out. As a SAC fat (painful as that is these days), I'm pretty much ready to deal him. He's hard to watch when he's angry or pouting - which is most of the season so far.
I'll do this trade in a heartbeat. Durant is a great leader. Cousins needs a good role model. I am sure He's gonna be a valuable player on a contending team ala Dennis Rodman (1996-98), and Rasheed Wallace (2004-2006)
