He is already maxed out when it comes to how much quality weight he can put on.
The "average" NFL offensive tackle is around 320 lbs.
He's a relatively skinny fellow, and the 300 lb weight listed is overly generous. He's much closer to 290 lbs.
There was one site that listed him at 306 lbs, but the only way that's accurate is if you add in the weight of his pads and helmet. If he were a true 306 lbs, then he would have certainly been drafted.
Keep in mind, in 2024, he was playing at 285 lbs, and he was having a lot of trouble adding weight to his frame. What we see him at now, is the result of Loren Landow's tireless work to get him into the best possible physical shape.
If his technique and athletic ability are enough to compensate for the lack of bulk, then I think he can end up having a very productive career, in a similar manner to Chris Hubbard.
