I think the three games starting with the Lakers this weekend will be the true litmus test for how good the Rockets really are. LA, Boston, and NO is a real tough run of teams to get through.
Don't get me wrong, 20 straight is incredible, but without Yao I still think they're in trouble come playoff time. The big men in a long series are a huge factor in the playoffs and without somebody to counter Duncan, Bynum (if he's healthy), Boozer, even an old worn out Shaq, it's going to be tough for them to match up.
