There were several giveaways for me. Tommy beat out Liam when that position (RT) was open three years ago, despite many here wanting Liam. Our Line coach thought differently.
Then along came Hainsey, and everyone including the coaches went wild. Tommy still started and we did the weird thing of alternating them on different series. I checked the films. We scored WAY more when Tommy was in the game than Robert.
But Robert was viewed as a natural tackle and Tommy a guard, so that's the way it ultimately went. People were irrationally impatient with a guy who was being jerked around positionally, but Tommy still was mauling opponents more than the others --- he just didn't have all the guard pulling stuff down yet.
So here we are: Tommy's comfortable, the opponents aren't, and my "Big'un" is giving a bunch of them unwanted rides. Is he perfect? No; people are human. He is sadly only a really damm good lineman who once a game might make an "unforgivable" mistake (in the eyes of people who have never played high-level ball and hold people to the standard of Zach Martin.)
Go out and make the opponents miserable Big Man.
