"Getting depth is real important because we have one position where we don't have a legitimate starter from last year," Campo said. "We need to find some guys, and there are always battles for the backup spots because a lot of it is involved in special teams. These young guys really have a chance to make the team."

As for Wall, he made a name for himself at Texas Tech for being a hard-hitting defensive back, which should translate well into him playing special teams.

"I just view it as a great opportunity," Wall said. "Wherever they want me to play, I'm willing to. Whether it's on special teams, as a nickel back or even a cornerback, I want to show I can contribute. There's not a whole lot of depth there, and that's a window of opportunity. I need to make the best of it."
