Like quarterbacks on offense, someone on the defense has to relay the play calls and make adjustments at the line of scrimmage. Those responsibilities typically fall on a veteran player, but not always. If Los Angeles Chargers rookie linebacker Kenneth Murray has his way, he will have those duties in 2020.

"I made the calls and checks all three years," Murray said on the RapSheet and Friends podcast, highlighting his ability to quickly internalize a playbook at a young age.

Oklahoma, Murray's alma mater and a Big 12 powerhouse, has built its reputation in recent years for its high-flying offense. Still, the program improved defensively last season thanks in part to Murray's emergence as one of the nation's top linebackers.
