I would echo the sentiments about Horford. When he plays PF, he's one of the best in the league. When he plays C, he's still a good player but noticeably worse. This has been going on for years. Whatever benefit we get from putting another wing on the floor, it's negated by playing Al out of position. So stop doing it.
I realize injuries have made this more difficult, but we should absolutely play both Williams and Baynes at C for the majority of games when they are both healthy, and keep an eye on the buyout market.
Irving (30) / Brown (24) / Tatum (30) / Horford (28) / C (24)
Rozier (20) / Smart (22) / Hayward (20) / Morris (26) / C (16)
That should be our rotation, more or less, if we want to win games. One of those guys in the 2nd unit isn't going to like their minutes. Tough. They don't all add up to 48 because the guards are a *little bit* interchangeable and 8 minutes of a smaller center won't kill us. But trying to be the Warriors with our roster is killing us.
Wait, how is Horf at C noticeably worse? He has matchup issues with burly centers like Drummond sometimes, but our offense goes on turbo with him stretching the floor as a center, and his switch-ability helps our defense a lot too.
Regarding the OP, also hurts to have Horford on a minutes restriction.
