I don't know how long they have been healthy together,

and how could they play as a team. D'Antoni's system having Nash running everything, he needs to a. be familar with all the teamates, and know their moves and sweet spots b. have the ball in his hands more.

I don't get why Lakers got Nash and coach D. Kobe or LeBron, they never need a true play making PG, not to mention an over-the-hill Steve Nash. 

Anyways, I will let you worry about your Lakers, and I will worry about my Rockets:)
