So far I think I've seen To'omalatai and Singh rotate in the most. I've also seen Taumopeau. There is a lot of belief in Sani Tuala though-- who is redshirting this year as he is still really new to the game.
At offensive tackle will have two fantastic true freshman in Thomason and the kid who is committed from the midwest. However, it feels unrealistic either will be ready year one. That leaves Kaden Chidester (comes from a small Utah town, I imagine he has good measurables since he got a scholarship offer), Jake Griffin (Grimes recruit, had some lower tier PAC12 offers), and Iki Tupou (currently a true freshman this year; nephew of Sione Po'uha) as scholarship tackles that I'm aware of.
We will likely see a transfer or two. And maybe we'll be able to flip Dunn or Vete with how things are going this year.
