And people only said that Rondo was good because he had the Big Three. Once Garnett went out, Rondo really stepped it up. Once Allen fouled out in game 5, Rondo REALLY stepped it up. If anything, Rondo and Perk are held back stat-wise by being on a star-heavy team.
Of course their development had/has a lot to do with the Big Three and their championship experience, but by no means are they overrated because of who they play with.
