ARLINGTON, Tex. — Baker Mayfield was a walk-on at Texas Tech, and then a walk-on again at Oklahoma. And on Thursday night, he was the No. 1 overall pick in the N.F.L. draft, with the Cleveland Browns selecting Mayfield, the reigning Heisman Trophy winner, over three other highly regarded quarterbacks.
The others were Sam Darnold of Southern California who was picked third by the Jets; Josh Allen of Wyoming who went seventh to Buffalo after the Bills traded up to get to that slot; and Josh Rosen of U.C.L.A. who went 10th to the Arizona Cardinals, who also traded up.
