USC opened spring practice Tuesday, looking to formally turn the page on its tumultuous 2018 campaign and an offseason that brought its own share of setbacks.

New offensive coordinator Graham Harrell ran things from atop the baseball stadium, looking down on the field and wearing a headset to communicate.

And afterward, Helton and more than a dozen players talked about the first session, some of the events of the offseason and their expectations moving forward.
