I get that coaches are inherently on a different level than casual fans, but as a coach I don't really think he's anything special. He won with a stacked Celtics team where his fourth best player was a 40% 3 pt shooter who was a 7x all star before that year and eventual hall of famer, and he's been given a lot of stacked rosters and underachieved. If anything, his Celtics tenure was also mixed because that team had the talent where they could have easily won more than one. They had issues that weren't the coach, too, but it's hard to feel like he elevated them rather than just took the ride, and he's coasted a lot off of his time here.
