I think Chauncey is probably happier/more excited about going into this season than any other. Partly because he has experience now, but also because Dame is gone.
Why would that matter? Dame was holding back his coaching reputation a bit, in that its not really easy for Chauncey to instill his coaching style on a proven vet like Damian. Damian isn't going to change his game to match what Chauncey (or any other coach) wants or demands (cept for a coach like Pop), especially if that change is a drastic change from his bread and butter.
Now that the team has only 1 player who has been on the team more than a year, and only 1 real "vet", Grant, and mostly younger players (I know Williams, Simons and Ayton aren't youth, but they're not really at a place where they can get away with playing the way they want, like Damian could), he can coach players without the "I'm a superstar/all star/all nba" type mentality as an issue.
I'm going under the assumption that Brogdon isn't staying on the team. So outside of Grant, no one on the team has played more than 5 years, and 8 *!* players have 1 or less years of experience. Also including 4 from the 18 draft (Simons 24th pick, Ayton 1st pick, Knox 9th pick and Williams 27th pick). All are moldable pieces, far more than CJ, Nurk and Dame were or are.
If after this season he still sucks ass as a coach, then he should be shit canned.
