Vogt's +/- in the 2nd half was -1. But sure, he won us the game. Just like last year, even at his best, Vogt is generally a net neutral.
Temple was his best case scenario, a team with an undersized big, who can't shoot and (for some unknown reason, probably involving bad coaching) they tried to pound it inside anyway - where Vogt is actually good on defense. Even with all that going for him, he was -1 in the 2nd half (to be fair, he would have been +0 if not for techs). Since he was bad in the first half, that left him at -6 for the game (cancelled out by Diarra's +6).
Just like I said last year, Vogt just isn't that good. Vogt playing "well" is him not hurting the team too much. I want a center who is actually giving positive contributions and Vogt isn't that center and never will be. Diarra is the only viable center on the team for next year, he should be getting as many minutes as he can take. Especially when he outplays Vogt, which he did in the first half (and probably would have in the 2nd if he'd been given a chance).
As for Harvey, I agree he should be getting more minutes and if he doesn't soon I will add him to the guys I complain about not getting enough minutes. But 18 minutes in first game post Covid is about what I expected. I think he will get more minutes in the coming weeks.
