Lincoln Riley saw what Arizona did against USC in October and decided he wanted some of that.
On Monday wide receiver Dorian Singer became the third Arizona transfer to commit to USC, joining defensive tackle Kyon Barrs and cornerback Christian Roland-Wallace.
Singer led the Pac-12 with 1,105 receiving yards this season and posted a career scoring day against the Trojans, getting to the end zone three times on 141 yards.
The 6-foot-1 Singer gives Heisman winner Caleb Williams another top threat to throw to next season, not that Williams needed any more help.
