Lincoln Riley has been impressed with Arizona transfer Christian Roland-Wallace through the first five days of USC training camp.

The Trojans didn’t get to see much of the defensive back in the spring as he was battling an injury. But he’s been full-go for USC since fall camp opened and Riley seems excited about the defensive versatility he offers the secondary.

“Christian Roland-Wallace is a fun piece for us because of his experience and how smart he is, his skillset, he can play anywhere,” Riley said Wednesday. “I can see him playing corner, can see him playing nickel, can see him playing safety. He can play any of the five, which is a great thing.

“He’s certainly been impressive in camp. We didn’t get to see him much in spring, he got injured early, so it’s been nice to watch him. He’s been as advertised.”

Roland-Wallace started all 12 games at corner last season for Arizona. He notched career-highs in tackles (58), pass breakups (six), and forced fumbles (two). He was the Wildcats’ third highest-graded defender, according to Pro Football Focus, and played the second-most snaps of anyone on the defense.

In four seasons with the Wildcats, he had 18 pass breakups, 3.5 tackles for loss, two interceptions, two forced fumbles, and 1.5 sacks in 41 appearances. The opportunity was there this offseason for him to enter his name into the NFL Draft. Instead, he hit the transfer portal and made his way to USC.

The Trojans have open competition all over the secondary in camp. Mekhi Blackmon needs to be replaced at corner. Calen Bullock’s partner at safety is up for grabs and the Trojans are looking for someone to take hold of the nickel spot.

Roland-Wallace could eventually slot at nickel while Jacobe Covington and Ceyair Wright man the two corner spots.

Time will tell. USC opens the season on Aug. 26 against San Jose State.
