Bills signed Richmond QB Aaron Corp.
A five-star high school recruit, Corp originally enrolled at USC, but transferred after breaking his leg and losing the Trojans’ starting job to Matt Barkley. Corp looks the part at 6-foot-4, 215 pounds, but has had his athleticism sapped by multiple leg injuries, and is now a fairly run-of-the-mill pocket passer with only an average arm. He’ll compete for the Bills’ No. 3 job.
