Both were hurt for the spring. Reimer was out all spring and Gunnerson came back for like the last week and was limited. Don't think he played in the spring game, who knows how he will respond to all these injuries.
Reimer is a B1G player. Obviously took a step back last year but he can still be solid this year.
As for the rest of the list
Ru’Quan Buckley = Should get snaps this year, looked like he needed to work on his pad level.
Jimari Butler - Was in discussions all spring about increased PT, edge position is crowded though.
Randolph Kpai - Didn't hear much of anything about him in the spring. may be a transfer candidate
Dylan Rodgers - Still in high school
Garrett Snodgrass - Was out all last year with an injury. Did okay in the spring game but I don't think he has the speed for this scheme
Javin Wright - Also battling injuries/health issues. There was chatter about him pre-injury doing before that but haven't heard much since.
Stephon Wynn - Depth piece. Thought he was a big disappointment last year.
