NORMAN — For the first two hours of Oklahoma's pro day, Baker Mayfield was nearly invisible.
Wearing a black Nike sweatsuit and white Converse sneakers, Mayfield melted into the background, chatting with former Sooners, coaches and NFL scouts as he watched his teammates run the 40-yard dash, do the bench press and sprint through cone drills.
Standing on his numbers from the NFL Combine a week and a half earlier, the quarterback was merely a spectator and cheerleader for the early morning tests.
But make no mistake: Mayfield was the main attraction.
After relative anonymity in the controlled chaos of the Siegfried Strength and Conditioning Center, the reigning Heisman winner traded his Converses for Nike cleats and tied a white headband with a crimson Nike logo around his head.
