He played quarterback at Texas A&M,[1] where he finished his career 3rd all-time for the Aggies in rushing yards by a quarterback. As a freshman, Mosley replaced an injured David Walker against TCU and led the Aggies to victory in Fort Worth rushing for 96 yards and a touchdown in a 52–23 thrashing of the Horned Frogs. Mosley would not relinquish the job, becoming the Aggies' starting quarterback for the next three seasons.
Professional career
Mosley was selected as a receiver by the Buffalo Bills in the third round of the 1981 NFL draft.[2] During his first season, he was on injured reserve with a pulled hamstring.[2] In his second season he was a special teams standout as the team's kick returner.[2]
On October 30, 1983, Mosley came on during the second quarter as a substitute for injured wide receiver Jerry Butler, helping the Bills to victory against the New Orleans Saints with five catches for 59 yards and two touchdowns.[2]
Unfortunately, a series of injuries cut short his promising NFL career and forced Mosley to retire after the 1984 season.
