Rondo.
I have seen perfect games and no-hitters. There is always a measure of luck involved in a perfect game. Don't misread -- it is a unique and amazing feat -- but how different really is it than a 1-hitter (which we wouldn't even be talking about today)? That's right, one hit. One better placed ball off the bat.
Rondo's feat is astounding. Take 10 points, 8 rebounds and 3 assists away and we are still talking about an unbelievable game. And pure skill -- very little luck involved.
18 rebounds??? 6'1" ? Unreal.
I've seen amazing performances (Bird v. Dominique comes to mind), but what is extraordinary is that this was not only an all-around individual performance, but this was not a 'give it to Bird; give it to Lebron; give it to Dominique' performance. This was Rondo working within the team concept, sharing the ball, involving his teammates and dominating with the ball and on the boards.
It WAS a perfect game.
