Rondo's inconsistency as a whole is completely overblown. People have the most selective memories.
Seriously, I challenge someone to find any evidence that Rondo is any more inconsistent than any other star player. Even Durant and Lebron have bad games.
Look at Melo last night! He sucked. He scored 20 points, but not efficiently. Rondo, at least, has the sense to know when he is cold and doesn't just jack up shots for the sake of it.
