Too many variables with the Cavs to predict the series, but I'll stick with my gut feeling : Celtics in 6. Our biggest enemy, besides LeBron, is in the Celtics' minds. Fear the Cavs or think back about the previous series when they make a big run and we're done. Don't fear them, play our game relentlessly, like we did in the first two series, and we've got this - barring LeBron miracles.
Go Celtics, can't wait for the early tipoff!
