There's only one offensive lineman (whether it be T, G, or C) in the league who is better than Joe Alt is right now, and I'm actually OK with that, since it's Quenton Nelson.
It goes to show that 2021's sudden stabilization of what was a very shaky offensive line was because of Joe Alt stepping in as a true freshman, and playing like a polished 5th year senior.
As long as he stays healthy, he's going to finish his career with Hall of Fame credentials. That won't be for a very long time, though, since he's only 22 years old.
