Shaq will definately get you some easier looks at the basket. Shooter probably love the guy. Just don't play too well or the big man will get jealous. Just ask guys like Penny, Van Exel, and Kobe. Ever wonder why Shaq's best friends are guys that depend solely on him like Fisher and Dennis Scott?
Kidd does make his teammates better, but you have to go along with what he's doing to make it work. To be O'Neal's teammate means he passes you the ball wide-open, and you just shoot it. It's definately easier I think to be a role-player Laker than a role-player Net.
