The Super Bowl champion wide receiver for the New England Patriots shares his inspiring story of an underdog kid who was always doubted to becoming one of the most reliable and inspiring players in the NFL. When the Patriots were down 28-3 in Super Bowl LI, there was at least one player who refused to believe they would lose: Julian Edelman. And he said so. It wasn't only because of his belief in his teammates, led by the master of the comeback, his friend and quarterback Tom Brady-or the coaching staff run by the legendary Bill Belichick. It was also because he had been counted out in most of his life and career, and he had proved them all wrong. Whether it was in Pop Warner football, where his Redwood City, California, team won a national championship; in high school where he went from a 4'10", 95-pound freshman running back to quarterback for an undefeated Woodside High team; or college, where he rewrote records at Kent State as a dual-threat quarterback, Edelman far exceeded everyone's expectations. Everyone's expectations, that is, except his own and those of his father, who took extreme and unorthodox measures to drive Edelman to quiet the doubters with ferocious competitiveness. When he was drafted by the Patriots in the seventh round, the 5'10" college quarterback was asked to field punts and play wide receiver, though he'd never done either. But gradually, under the tutelage of a demanding coaching staff and countless hours of off-season training with Tom Brady, he became one of the NFL's most dynamic punt returners and top receivers who can deliver in the biggest games. Relentless is the story of Edelman's rise, and the continuing dominance of the Patriot dynasty, filled with memories of growing up with a father who was as demanding as any NFL coach, his near-constant fight to keep his intensity and competitiveness in check in high school and college, and his celebrated nine seasons with the Patriots. Julian shares insights into his relationships and rivalries, and his friendships with teammates such as Tom Brady, Wes Welker, Matt Slater, and Randy Moss. Finally, he reveals the story behind "the catch" and life on the inside of a team for the ages. Inspiring, honest, and unapologetic, Relentlessproves that the heart of a champion can never be measured.
