They grow up so fast.

With his 336 total yards in Nebraska’s 31-28 loss on Saturday, Adrian Martinez became the first quarterback in school history to tally 300-plus total yards in seven games.

Oh, and he’s just a true freshman.

The Cornhuskers may have finished 4-8 in Scott Frost’s debut season as head coach, but they went 4-2 during the second-half stretch, with Martinez a main catalyst for the late success. Four of his seven 300-plus yard games came in his final six appearances as the offense torched opponents for 36.7 points.

Martinez ended his freshman campaign 224-of-347 (64.6 percent) with 2,617 yards, 17 touchdowns and eight interceptions, adding 629 yards and eight more scores on the ground.

The next two-to-three years in Lincoln are going to be a lot of fun.
