I still don't think we know much about how the team will play against an opponent. That said, from what we saw at CTC and what we are hearing in addition, it seems like we are in the familiar position where our locks to start will be heavily relied on, and the remainder of the roster will evolve over the season and be used situationally.
We are hearing our defense is ahead of our offense; maybe the starters can cover for Kon on defense sufficiently that his potential as a shot-maker/creator to get our offense going from opening tip can justify starting. Maybe Flagg is still learning how to be assertive on offense at this level, or Jon is still learning how to use him, and we need some additional shot-creation for the time being; maybe Flagg's play shifts later on such that parking Gillis in the corner, which seemed to be his offensive role at CTC, is productive enough that his defense pushes him past Kon into more playing time. Maybe Jon wants a Mighty Ducks 2-style Bash Brother change of pace substitution at the 12 min mark and brings both Sion and Gillis on to stymie opposition. Maybe we end up having to play smaller than expected and Gillis sees more time as a smallball 4 with Flagg or Brown.
As useful as observations from early season practices can be, and I am grateful to Jason and others for sharing them, we won't really know what this team will look like until they play a few games. As Donald is fond of reminding the podcast listeners , in the words of that sage of our times, Mike Tyson: everyone has a plan until they get punched in the mouth. This team offers numerous potential adjustments, though, so I am excited to see how we deploy tactically throughout a game.
Re Roach's performance on the 22-23 final four team, Tennessee would like a word (ugh). And if we are talking instead of 21-22, I agree with the above that Roach wasn't a difference down the stretch as a point guard/distributor, i.e. driving the Duke car, but as a scoring guard/shotmaker who scored in clutch spots in the tournament. Postseason Roach was a real thing, but IIRC (first time for everything!), that team often distributed by committee with Wendell, Paolo, and Jeremy all taking a hand in moving the team through its offense. We may see something similar this year, but I think that too much of that could be seen as an unwelcome development, particularly as it relates to Tyrese's play.
