I'd go with Noah/Griffin/Jennings, Griffin is already close to Amar'e's level. And Amar'e is on the downward slope of his career, meanwhile Griffin will become more of a quality defensive player as well as a better board man.
Noah and Gay are a wash to me and I like Jennings better than Stuckey now and going forward.
I don't blame you for making that move, because no one had seen Griffin in the NBA yet.
