I'm honestly surprised he hasn't taken a Perk-style flooring already. That kind of stuff used to be routine in the playoffs against little guys who got to the rim.
Say what you will about the flagrant rules and how they're applied, but they've cut back dramatically on the number of cheap shots you see, even in the playoffs. That's a good thing to me as a fan.
That said, Isaiah better keep his head on a swivel anyway, because someone's bound to have that bright idea after he embarrassed them in the paint on Sunday.
