Maybe slightly off topic, but the one thing I took from Brad Stevens was it didn't seem like he discourages younger players from playing their game. So I don't think we'll see Olynyk parked in the corner all game not doing anything like he probably would had done under Doc.
Perhaps I'm being a Debbie Downer again, but this team I watched yesterday had no idea (1) what their best shots are, and (2) how to go about getting them. They ran some sort of an offense and took some sort of shots, but it looked like a glorified pick-up game effort.
Rip all you want on Doc for forcing players into rigid roles, but Doc had a game plan, and Stevens doesn't. At least not so far.
It seemed to me that they were taking smart shots, they just weren't connecting with them. But, to be fair I could only watch the first quarter so I'm not sure about the rest of the game.
Individually, perhaps they were taking good shots, if this makes any sense. I just don't feel like they have, as a group, a notion of what their best shots are. This may sound counterintuitive, but there is a subtle difference between the two.
For example, while a wide open three-pointer for Courtney Lee is undoubtedly a good shot for him, your Celtics of years past were fully aware that their best shots were a KG fade-away from the right post, a KG spot-up at the elbow, and Pierce mid-range pull-up. So their offence was geared to try to get these first, and if it doesn't work, make sure they're getting a good shot (e.g. said open three-pointer).
This version of the Celtics strikes me as a team that passes the ball around without a clear idea of what they want to run on the offense. Or, in other words, no-one seems to have a clear idea what works.
Perhaps it's preseason, or perhaps it's the fact that it's the first game, and maybe I'm reading too much into it -- but that's what I saw.
