He's having a good year for the most part, but he really has nothing to gain by staying for another year, unless he absolutely dominates his matchups.
Give how he's a smaller tackle in today's game ("only" 291 lbs), it's extremely unlikely he'd be a day one pick even if he had a dominating year in 2026.
While 290-ish lb offensive linemen were considered big back in the 80's and even 90's, today's offensive linemen are at least 20 pounds heavier, and just as athletic.
Right now, he's being seen as a day three pick by most scouts, because he lacks the physical bulk and strength that most right tackles have. I don't think that he has much more room to pack on more quality pounds, since he's actually a pretty lean, skinny fellow (for that size), who does most of his work with speed and technique.
My best guess is that if he were to stay for a 5th year and wanted to significantly improve his draft standing, he'd have to play left tackle, and improve his footwork. That would seem to be a much more natural fit for him.
This way, move Anthonie Knapp to guard or center, which would also be a better fit for him.
