I understand the paranoia, but it would be pretty surprising for Rondo to be suspended. Yeah, it was a classless move by Rondo and an easy flagrant call, but pushing someone when they are not in a vulnerable position is not that big of a deal. It was very Kenyon Martin-esque, and even Kenyon doesn't get ejected for those kinds of plays.
I don't think the Bulls care much about that play either.
