There are going to be so many games like this during the season. The Celtics are going to just jog around and destroy the majority of their opponents...then the bench is going to come in and destroy the opponent's bench.
As the games roll by, the Cav's, Warriors et al are not going to improve...The Celtics though, are going to improve a great deal.
You're playing the Celtics down 11 with 3 minutes to go in the first quarter and Smart, Rozier and Morris/Tatum (or whomever) rotate in. Few NBA teams have an answer for that.
Maybe they won't win it all, but, they will scare the bejesus out of whomever does.
