Nebraska coach Mike Riley hasn’t had a chance to scout UCLA in depth yet, but knew the reputation of at least one player: Josh Rosen.

Riley will be coaching against the Bruins and their “outstanding freshman quarterback” — as he said of Rosen on Monday — on Dec. 26 in the Foster Farms Bowl in Santa Clara. The former Oregon State coach recently talked to Washington’s Chris Petersen, who said of Rosen: “That guy is for real.”

Riley’s Nebraska tenure started off with a loss thanks to another freshman quarterback in BYU’s Tanner Mangum. Relieving injured starter Taysom Hill, Mangum ended his debut appearance with a 42-yard Hail Mary, giving the Cougars a 33-28 win in Lincoln, Neb.

Mangum finished the regular season with 21 touchdowns and seven interceptions, completing 62.1 percent of his passes for 3,062 yards. Rosen heads into his first bowl game with 20 touchdowns and nine interceptions to go with 3,350 yards on 59.5 percent passing.
