You gotta put Nash in at the end of the game. He's the two time MVP, the team's best clutch shooter, and our spiritual leader. Also, Goran had just bricked an open three. Putting them both in at the same time would've been interesting, but I think after J-Rich hit the tying shot the other day, he earned Coach's support. The only decision I think you can quibble with is substituting out Dudley for Hill. Duds is the better three point shooter, and had been playing better defense.
And Channing Frye has earned a contract extension. Amare has not, and that was painfully obvious to anybody who watched the game. Hopefully he'll do well somewhere else (but not against the Suns of course).
