There’s no shortage of blame to go around when it comes to the 2018-19 Boston Celtics.

From Kyrie Irving’s hot-and-cold play (and equally hot-and-cold behavior) to Terry Rozier’s claim that nobody sacrificed more than he did in an attempt to make it work for this year’s Green, the Celtics were a complete mess. So much so that even team owner Wyc Grousbeck admitted that he had a hard time loving this team.

But nobody took the Celtics’ disappointing season harder than head coach Brad Stevens, according to ex-C’s assistant Micah Shrewsberry.

“I think [Stevens] really beat himself up,” Shrewsberry told the Boston Globe’s Adam Himmelsbach in a phone interview

“Even when he was doing a great job, even when he was putting everything toward it, he still looked toward himself during all those moments. Hopefully guys appreciated that,” Shrewsberry said. “He was always looking for ways to fix our problems and saying, ‘How can I be better to help these guys be more successful?’”

Shrewsberry, who had been with Stevens since Stevens made the jump to the NBA six years ago and recently departed to return as Purdue’s assistant coach, also said that Stevens has already refocused his energy on improving next year’s C’s.

“He’s definitely locked in,” Shrewsberry told Himmelsbach. “He’s back to reading all the quotes and seeing what the best teams are doing. ‘Here’s where we failed, here’s how we’re going to correct it, and we’ll get to the roster when it happens.’

“He’s all the way back and locked into next year and being ready, like, let’s have a great one next year.”

Now the big question becomes who will be on Stevens’ team, as the Celtics are set to enter one crazy summer headlined by the pending free agency of Irving.
