Yeah, he is, and we're in trouble. Rondo has been BAD lately. Even when he's good, he's very limited. I'm not convinced a team with Rondo as its MVP can win a title.
They were a pathetic Ray Allen away from winning the title with Rondo as finals MVP.
They were a decent rebounding front court and a crunch-time offense that can actually score away from winning it all with probably Paul getting finals MVP. If you'll recall, Rondo only actually had one or two really solid games in the Finals because he burnt himself out carrying the team through the 2nd round (and the ECF).
That's my point, really. Even when he's playing his best, Rondo can only sustain that kind of play for short periods of time. He doesn't have the stamina to carry a team over a long period (even for more than a series or two) because it requires so much sacrifice of his body to carry the team.
He doesn't have the strength or size of a player like Wade, Westbrook, or Rose or the offensive skills of a player like Chris Paul, Deron Williams, or Steve Nash to consistently dominate without totally sacrificing his body.
