Rondo also pushed Hinrich to the scorers table out of frustration. I don't see much of a difference between the two plays.
If it was me, I wouldn't suspend players for this kind of plays - as long as the situations don't escalate. In my view, plays like, say, the one from Bynum on Gerald Wallace are much more deserving of a suspension, in spite of looking less serious: they can be merely reckless, but they are also much more dangerous.
Anyway, if the league suspended Garnett for that skirmish with Bogut, how can they now justify not suspending Alston? The same for Kobe. Fisher I think they will suspend him either way.
They should start being more consistent though.
