Hour after hour, Tyree Jackson would sit watching YouTube highlights of great quarterbacks at his home in Norton Shores, Michigan. Tom Brady was a favorite. Jackson would watch the way he moved. The angle of his arm. How he gripped the ball. He'd memorize every detail. Then he'd move to the backyard, where he had a tire hanging by a rope from a tree, and throw and throw and throw and turn himself into a quarterback.
That's how he built the arm that led to one of the greatest careers in Michigan high school history, starting all four years at Mona Shores High and finishing fourth in state history in yardage and third in touchdowns.
