Amorion Walker came to Michigan as a WR, then flipped to CB to help fill depth in that area. He struggled in the Spring Game and Michigan hit the portal to find UMass Josh Wallace to play across from Will Johnson. That worked out well and Walker only saw limited time at CB.
Walker got a bit frustrated and transferred to Ole Miss to restart his football career during the off season. Then it became clear Michigan needed WR bodies due to other transfers and the NFL. Walker re-entered the portal and came back home to Ann Arbor.
