Jack Kemp

Jack Kemp laid the Bills' AFL foundation with two championships and every club passing mark in his day, while Josh Allen's still scripting his epic, dual-threat saga in the Super Bowl chase—Kemp's the grizzled trailblazer, Allen the freight train building toward immortality, but neither's sniffed Canton yet.

Nope, Jack Kemp's not in the Pro Football Hall of Fame, despite seven Pro Bowls, an AFL MVP split, and quarterbacking Buffalo to back-to-back titles in '64-'65—his 21,218 yards and grit got overlooked in the Canton shuffle, a quirky snub for a guy who owned the early Bills.

Kemp's cannon arm and mobility would've feasted under today's pass-happy rules—no more leather helmets or assassinations on QBs. Picture his 46.7% completion popping to 65% with RPOs and quick releases; he'd scramble like a proto-Allen, racking up 4,000-yard seasons in this protection paradise.

Kemp and Jim Kelly both owned the Bills huddle, but Kelly's 49.97 passer rating smoked Kemp's 25.39 in the stat sheets—Kemp scrapped through the brutal AFL with 114 TDs and titles, while Kelly's gunslinger precision lit up the '90s; think old-school brawler versus smooth operator.
