One of the most basic transitions that both head coach Kliff Kingsbury and rookie quarterback Kyler Murray have had to make this year going from college to the NFL is within their pre-snap world.

In both the way Kingsbury ran his offense at Texas Tech and the way Murray ran Lincoln Riley's offense at Oklahoma, hand signals were used. Kingsbury has worked with the headset and calling in plays to Murray's in-helmet radio. Murray has had to learn how to spit the play out to his teammates.

"We've really, really worked on that," said Kingsbury, who admitted he has accidentally been ready to use hand signals every now and then. "Kyler is used to seeing the visuals on the sideline, Lincoln would give it to him, he'd give it out. Both of us are working through that process. We really hammered in throughout the spring, and every opportunity we can this fall as well."

Kingsbury went to the sideline with the headset as soon as he could during OTAs and minicamps, to get a feel of what it would be like in game situations (play-calling predecessors Bruce Arians and Mike McCoy each simply used a walkie-talkie and stood behind the plays during offseason work.)

The way college football is going, many quarterbacks have had to deal with the NFL transition from sideline hand signals. Murray acknowledged it's been the hardest part of moving to this level.

"Having to deliver it all to everyone while coach Kingsbury is still talking in my ear, trying to focus saying things to the line and giving signals to the receivers, that's probably the biggest adjustment," Murray said. "Coming from college where you get one signal and you already know what everyone is going to be doing ... it's a neat deal. Just takes some getting used to a little bit."
