Thon Maker has been a disaster this year, that Raptor series tricked us all to be honest and he has a long long way to go, he realistically shouldn't even be part of the rotation anymore. To put it in perspective of how bad he's been, he's currently the worst rebounding starting C in the league, even on a per minute basis he's been horrific to the point Meyers Leonard had been better on the glass. They are getting absolutely nothing from him, the popular thought is that he helps their defense, yet they have a 115 defensive rating when he's on the floor and a 99 when he's off it, even their offense improves without him. The only thing he provides is the threat of three point shooting, outside of that he probably needs to be playing in the G league. I don't know how he's going to get better this year either, a lot of his problems come from being so skinny and weak, dudes just toss him out the way for boards. Then there's Khris Middleton, who is a nice player and asking him to be a 2nd option isn't in his bag, Brogdon is a roleplayer that has a cap on what he can give you and a very low ceiling. After that they have absolutely no other players on the team that can create offense from the perimeter.
They need another creator in the worst way, what they have now wont cut it, and I'd really worry about Giannis staying there long term. It's never too soon to worry about your franchise player, and he already said some shyt over the summer about how he's loyal and would prefer to stay in Milwaukee but the organization has to make the right moves. That clock is ticking, and we've seen the movie play out before where a perimeter player is asked to do too much and then decides to leave.
