USC could be finished recruiting quarterbacks in the 2016 class.
The Trojans are expected to sign one player at the position after Ricky Town and Sam Darnold signed in 2015.

Fink, 6 feet 3 and 185 pounds, passed for 1,386 yards and 10 touchdowns, with three interceptions, during the 2014 season. He also rushed for 725 yards and 10 touchdowns in 75 carries.
USC also made offers to Malik Henry, Shea Patterson and K.J. Costello.
