Rondo is still really young. He's put up monstrous games in the playoffs, games so good they've compared him to the all-time greats. Better yet, statistically, his 29 point game was the 3rd best triple double in NBA playoff history. Sure, a lot of that has to do with the guys on his team, but the rest of the team hasn't exactly been consistent.
He has a lot of plays that are in the highlight reels, but he's not quite there yet. In two years, he'll be the best point guard in the league, but he needs some work on his jumpshot first.
