Hahaha you guys are joking right? Rondo's not tall enough to block the ball on that play. He put his hands up and got him on the forearm so he'd miss the shot but didn't push or shove him at all resulting in Landry landing his feet. Didn't even look like he even made any contact on the body.
No different than 90% of fast break fouls.
The NBA is a freakin joke.
