Sure, you can have a shorter "center".
But only if your offense doesn't rely on having a tall/power center.
If the offense is predicated on up-tempo, 3pt shooting then you don't need a tall/post center.
I don't really see the value in comparing a Rutgers center to a Baylor or Houston Center unless we are going to run a similar offense.
We're not going to run that sort of offense full-time, because we have Cliff Omoruyi. But I think we'll see different styles with different lineups. In the Pikiell era he's always had two stand-in-the-paint bigs... Doorson and Johnson, then Johnson and Carter, then Johnson and Omoruyi.
Texas Tech had 6'7" Marcos Santos-Silva at center and were 316th in tempo and 305th in 3-point attempts. It can be done. Hyatt or Mag (or Harper, but I don't think he'd be asked to) could potentially play as a small-ball center for two 3:00 stretches a game. Figure Dean Reiber gets 6-8 minutes and you hope Cliff can give you the other 26-28 minutes. (To be clear, Hyatt/Mag would not be as effective as Santos-Silva but that's not the point... Santos-Silva was playing 20+ minutes at center, I'm saying we play this way for 6-8 minutes a game)
The way the team runs offense with the non-Cliff lineups will be different than the Cliff lineup. With experienced guys like Baker and Mulcahy to initiate the offense, it can be done. And then you let Jaden Jones do his thing in more basic sets with Cliff in there.
I wouldn't run the small-ball lineup against, like, Trevion Williams or Hunter Dickinson. They're too good in the post that even with a double team they'd make something good happen. But I would run it against Zach Edey and force him to defend at the 3 point line. I'd run it against Josh Ogundele or whoever Iowa has replacing Garza.
