Most people know about quarterbacks and the number 12. Even if you didn’t know where it started — Al Dorow of the New York Titans made the Pro Bowl in ’61 wearing number 12, while Charley Johnson of the St. Louis Cardinals was the first #12 to throw for 3,000 yards, doing so in 1963 and 1964 — you can probably recite most of the history from there. John Brodie, who entered the NFL in 1957, was the first great #12, while Joe Namath took the number to iconic status in the late ’60s. It was popularized by Roger Staubach (who also wore 12 at Navy in the early ’60s), Bob Griese, Terry Bradshaw, and Ken Stabler in the ’70s. That means the Super Bowl winning quarterback wore #12 for nine straight years, beginning with Super Bowl VI. Doug Williams even wore it in Tampa Bay, although punter Steve Cox forced Williams to don #17 when in Washington.

Lynn Dickey wore it for the Packers in the early ’80s, while Randall Cunningham and Jim Kelly repped #12 later in the decade. Stan Humphries made it to the Super Bowl wearing #12 with the Chargers, while Erik Kramer set the still-standing franchise records for passing yards and passing touchdowns in a season while wearing #12 for the Bears in 1995. The only time a Ravens quarterback threw for 4,000 yards or 30 touchdowns was when Vinny Testaverde wore #12 in 1996. Chris Chandler took the Falcons to the Super Bowl in 1998 wearing #12, while Rich Gannon became the second great Raiders quarterback to wear twelve a year later.

And since then, three guys you might have heard of have worn #12: Tom Brady, Aaron Rodgers, and Andrew Luck.

Since 1950, players wearing #12 have thrown for 675,044 yards. No other number has yet to hit the 500,000-yard mark. But that brings us to today’s trivia: Which number has produced the second most passing yards since 1950?

Trivia hint 1 SelectShow> In 2014, there were six quarterbacks who started a game and wore this number, with three of them starting at least 13 games.

Trivia hint 2 SelectShow> Only once has a quarterback wearing this number topped the 4500-yard mark, but that quarterback threw for 4,952 yards and 32 touchdowns.

Trivia hint 3 SelectShow> This one’s for John.

Two more notes:

Punter/receiver/defensive end Horace Gillom was a good player with the Browns for nine years. And in 1950, Gillom, who wore #59, completed a 3-yard pass.

The largest number to gain any passing yards in the NFL is number 89. It was worn most prominently by Frank Wycheck, who threw for 148 yards in his career, even if his most famous pass never gained any passing yards.

And no, there has yet to be a player wearing a number in the 90s who has thrown for any passing yards. You’re up, J.J. Watt.
