Watch USC introduce Lincoln Riley as its new football coach

USC sent shock waves through the L.A. sports landscape and the college football world Sunday when it hired Oklahoma's Lincoln Riley as its football coach.

Of all the potential candidates who emerged in the weeks and months after USC's firing of Clay Helton, Riley was never considered to be on USC athletic director Mike Bohn's radar for the job. That assumption was proved wrong Sunday, with the Trojans' whirlwind pursuit of Riley leading to a signed contract.

Now that Trojans fans have gotten over the initial surprise, USC can start with the formalities.

The university formally introduced Riley as its new coach during a news conference Monday afternoon.
