re: Has there ever been a pos switch (for lack of depth) that's worked out for that player?

for Michigan, we've had a few in recent years:

Hassan haskins - Currently with the Titans. started out at LB, but we were thin/unproductive at RB, and become arguably the best RB at UM in the past 25 years

Mikey Sainristil - started out at WR, then switched to DB/NB because of a glut of WRs that we had for the 2022 season. might be one of the most impactful defenders UM has had this century, and should be drafted in the top 2 rounds

Kalel Mullings - played LB, but blake corum got hurt late in 2022, and Mullings switched to RB the week of the OSU game and threw the ball on a trick play in Columbus. I'm expecting him to big things this year, as he's a more traditional, big 10 powerback with very good speed
