Billups and Prince for TMac would be a fantastic deal for the Rockets. Billups/Battier/Prince/Scola/Yao? Sign me up.
And on the other hand, Detroit gets to still make a run for the title for a few more years, as opposed to blowing it all up now and building on the fly around Stuckey, Prince, and Maxiell. Stuckey/Rip/TMac/Sheed/McDyess with Maxiell off the bench is still very dangerous.
