Jafar Armstrong joined the Notre Dame football team before the 2017 season. After redshirting his first year on campus, Armstrong made the switch from wide receiver to running back, helping the Irish fill a serious void on the roster.
The result was a relative success, with Armstrong running the ball 72 times for 383 yards, which amounts to about 5.3 yards per carry. Armstrong also added 7 touchdowns. Armstrong say plenty of carries early in the season, but was hampered throughout the middle of the year due to a knee injury. The return of Dexter Williams also took away from Armstrong’s numbers, as the senior ball-carrier returned and took over as the lead back.
