I'd be surprised if Gasol isn't super cautious with this concussion. He has a strong medical background and isn't going to mess with possible long term impact to his brain. And he shouldn't, even if the Lakers have to play Nash at center.
Torn labrum for Howard sounds serious. I wonder if D Ho might just decide that the lights in LA are too bright for him and just go play for Mark Cuban. This summer, the Lakers can save his salary slot and weaken the Clippers by aggreeing to a S and T with Dallas where they take Marion's expiring $9m deal and sign FA OJ Mayo.
Then Dallas will have the caproom to sign Chris Paul. The Lakers can move Marion's expiring deal in season in another Pau deal from a team with a disgruntled big and cap issues.
