Logan Brown did not enroll early. It's highly doubtful that he sees time this year, except for maybe in jumbo packages. Probably not worth burning a 'shirt over though, so 4 games max.
JD was a trooper. Played through a ton of injuries. But, last season, I think Cole Van Lanen played more snaps at LT even though JD was the "starter" at the position. And CVL turned out to be the highest graded lineman on the team. So LT is good. Beach played really well at RT when David Edwards went down. As in, really well. OL is not a concern of mine right now.
