The last two years have been a study of Brad Stevens. Think about it, for the last 164 games, he has been the only constant on this team.
The first half of this season, his roster would not let him play "his" system and there was little he could do about it. The team was lottery bound and our debates related to "percentage possibilities" for getting the #1-#3 pick.
Early this season I watched Pressey, Smart et al dig the regulars out of a loss against the Wiz and Stevens leaving the bench in for OT while the starters watched. The bench throughout the season has always epitomized the "Stevens way."
Once the trades were complete, the coach had 100% buy in. The guys started to play for each other. The starters tend to suffer against good NBA teams, but, once the bench gets in? They wear them down.
It is a very entertaining brand of ball. No Celtics player is "key." They have won with each of them out for injuries or otherwise.
I hate to lay the reason for success at any one person's feet as it is a team sport, but, at the ends of these games? There isn't a coach in the NBA who wants to go up against Stevens. He doesn't have any stars to worry about so he rotates 9 guys four times in 43 seconds of play.
Team that is hot and has nothing to lose, very dangerous.
Stevens has created an android basketball player named "Marcus Thomas." Ridiculous offensive skills and a mad man on defense. Just where you gonna get that?
