I don't see why not. What is the benefit of starting Theis if Sengun is better? I doubt Sengun's confidence is going to be shattered if he's lined up against other NBA starters. He's played professional basketball already, he isn't a prospect that's coming straight out of high school and getting his feet wet. I think he'll start within the first month of the season.
Alperen Sengun impact as a Low Post Player, Passer, Using his Body to get those Muscle Rebounds, His High IQ is at the same Level as Jokic. He is a Superstar that makes a Impact. The problem with KPJ and Jalen is they are getting pressured by bigger defenders in the backcourt and Theis has no offensive game. Alperen Sengun checks in, literally the whole floor opens up with his passing, muscle post moves his shooting. Making Teammates better. Jalen and KPJ can thrive if Alperen starts, Wood can play better too.
Yes, he would help with some of the playmaking issues and drastically upgrade the toughness of that unit.
Just nut up and start Sengun with Wood. If going to tank then experiment while doing so. Play Green in 2nd unit with his mentor, Theis, who is allergic to the paint anyway.
Sengun and Garuba is our future starting 5/4 but I'm not in a hurry. Sengun looks like he watched Theis for a week and downloaded all his experience haha Right now Wood should be taking the most shots by far, he's our most efficient scorer. Silas will destroy woods value if he treats him like a two way balanced player. Wood has to score for his net impact to be positive. Don't make the mistake Dallas made with Porzingis, people are who they are, if his strength is offense and he's the most efficient scorer then give him shots.
I'd start Theis but let Sengun play 20-30 mpg immediately. He will earn the starting spot soon enough tho, but you can't just give it to the rook.
