I think using his playoff record is a poor indicator.
he had no talent the first two years he made the playoffs and they faced the cavs in the first round both years. Last years team certainly overachieved as you saw how they got steamrolled over by the cavs. But they still made the ECF
now, we are up 2-0 in a series playing guys like Rozier/Tatum/Brown putting up big numbers. Before the first game the nba analysts were saying it wouldnt be an upset for the celtics to lose.
lets see what Brad can do next year when you have tatum/Brown with more development and add two all-stars in Irving/Hayward to the mix. I think it will be beautiful to watch.
