I think it is weird to look at the Warriors series and see a fatally flawed Celtic team, as some people seem to. Ime is one year into his tenure as coach. The Celtics were less then 5 months in to playing the way he wanted them to, and they were dealing with injuries to at least 3 starters (Rob, Smart, Tatum). One key guy was relatively new here (White). There's no reason to think Tatum has peaked or that this iteration of the Celtics has peaked. I mean, it is less than 5 months into this iteration of the Celtics finally playing well, and some are already predicting that the sky is falling?
Brad has shown himself to be far less reluctant than Danny to make moves, so I expect the team to look somewhat different this time next year.
But if they made no moves whatsoever and ran it back with the exact same 15 guys, they could be a #1 seed, ECF favorite, and champion.
I think Ime is a great coach, but I think he was outcoached by Spoelstra and Kerr, both of whom have a lot more experience than him. He made some game 6 adjustments to his rotations that went over like a lead ballon and keyed the Warriors 35-8 stretch that all but put the game away. Some of that was lack of options, of course, but Ime wasn't forced in game 6 to do anything he hadn't done in 1 through 5. I expect him to imprve as well in his second year.
My biggest concerns about this team are 1) Rob's injury, 2) the short offseason, 3) Horford's age. Those aside, there are no problems here that Brad can't fix.
