The 07-'08 Rockets team is an odd choice.
The 08-09 Rockets was their best roster of that era (Yao, T-Mac, Artest, Battier, Scola, etc) and went the farthest in the playoffs: 2nd round taking the Lakers to 7 games and pretty much Yao Ming's defining year and swan song appearance with how he pretty much broke his foot/ended his career trying to will his team past LA, after taking down Portland in the 1st round.
It allows for Stevie Franchise to make it in, though.
