The Rockets are losing tonight because they are missing their second and third best players, and an important defensive wing. Add in little depth and the next few games are likely loses. Having said that, DMO isn't even close to the answer to the Rockets problems. He can stay in China where he is scoring 22 points a game while greats like Darius Adams and Jonathan Gibson are scoring 40 points a game.
I don't think it's crazy to say that DMo could help this team in that he's a player D'Antoni would actually play which would lead to more rest for players in rotation and him having some ability to create for himself could help when things get stagnant (which is only a problem with CP3 out)....but DMo is happy in China making more money there than he did here and the Rockets will be fine once their players get healthy.
