Not highly recruited.
But the stage, the game and the moment to start in his first collegiate game didn't affect the Lake Travis, Texas native.
"No he's not, he's not easily intimidated at all," Co-Offensive Coordinator and Outside Receivers coach Sonny Cumbie said. "Which is a great trait to have at quarterback."
Mayfield, the Big 12 Conference Offensive Player of the Week, finished the game going 43-for-60 for 413 yards, five touchdowns, four passing and one rushing, and no interceptions.
With that kind of performance Cumbie said you couldn't tell it was a freshman out on the field at quarterback for the Red Raiders.
"I thought Baker (Mayfield) played really well," Cumbie said. "We've seen all camp long with both of those guys for being freshman, they sure don't play like it. He's got just a charisma about him out on the field. He's kind of a gunslinger out there. He did a really good job, there wasn't a time that you looked out there and he looked like a freshman, he wasn't wide-eyed at all, the moment wasn't to big for him."
Not only was Mayfield's arm impressive in his collegiate debut but also drawing attention was his ability to move in the pocket and run.
The most excited moment Mayfield created with his feet in the game was an 11-yard run for a touchdown where he evaded defenders and finished the run off by leaping into the endzone and throwing his guns up as an exclamation point.
"Really, really excited to watch him play," Cumbie said. "He's able to create some things outside the pocket for us, which is big for us in this offense. This makes us a little more difficult to defend, but did a good job leading, making plays and taking care of the football."
When it comes to his passing ability Mayfield connected with 11 different receivers throughout the game.
Mayfield's favorite target at the end of the night was Eric Ward who recorded 13 catches for 150 yards to lead the team. Behind ward was Jordan Davis recording five catches for 70 yards and a touchdown.
That kind of synergy with the wide receivers Cumbie said comes partly because the way Mayfield carries himself on and off the field.
"He's a likeable kid," Cumbie said. "Anytime you have success at quarterback your going to draw closer to those receivers. As long as you're a guy that can get them the ball, your going to play for you no matter who you are. He's a guy that has that charisma about him, guys like him off the field as well as on the field because he's making plays and getting the ball to them."
When asked if Mayfield would get the start in the Red Raiders upcoming game against Stephen F. Austin on Saturday at Jones AT&T Stadium, Cumbie chuckled saying that decision is above his pay grade.
But the one thing that Cumbie would say about the young gunslinger is that he plays because he loves the game and the team he is representing every time he pulls his uniform and helmet on.
"He's out there just playing hard," Cumbie said. "I think he's very passionate about football. He loves football, he loves to compete and I think that's what he's out there doing. He's playing with a bunch of guys he feels good about and playing as hard as he can."
