Well, the NBA has drawn the proverbial line in the sand. I have no problems with the suspensions Kobe received (other than I think it's bullshit), but if the NBA is going to judge that action by Bryant as suspension-worthy, then that's how it's going to be. If Kobe repeats it, he should be suspended for multiple games. The NBA has clearly delineated what's acceptable and not acceptable, and it's up to Bryant to adjust to the rules.
However, having made this decision, the NBA has to be consistent in its calls from here on out. If Stu Jackson deems the action (of flailing one's arms or "driving a stiff arm back") as illegal, then the action merits suspensions, not the consequences. That is, players should now be at risk for suspensions if the commit such an act, regardless of consequence, since Stu Jackson has made it clear, he is not judging Kobe's intentions, only what he sees on the screen.
And therein lies the quandary that the league has put itself. Should all "flops" now be suspension worthy? What about players who drive to the basket and flail their arms out after getting fouled and nail a defender in the forhead with an elbow (which Mike Miller did prior to Kobe Bryant cold-cocking him in that famous incident)? Does the NBA suspend only when the action leads to contact/injury? Because that certainly doesn't seem like judging the action on its own terms.
When you make a statement as the NBA did on Kobe's "follow-through/flop", then it's imperitive that you stay consistent to the standard. And if this is the decision that the NBA makes, that you can't just haphazardously flail your arms when you get fouled/blocked, then how will that affect the game?
Actually, it might change it for the better, since it could conceivably cut down on overt flops. On the other hand, it could leave too much up to perception since officials will now have to look at each action as legitimate or flopping, which in turn would slow down the action.
I think that's the real issue here.
