We know it’s a historic seventh Super Bowl for the New England Patriots' pair of quarterback Tom Brady and coach Bill Belichick, but here are seven facts you probably didn’t know about them.

Always a close game

The Patriots’ six Super Bowls with Brady and Belichick have each been decided by four points or fewer. Only seven of the other 44 Super Bowls have been decided by four points or fewer.

The magic number is 11

Brady has thrown touchdown passes to 11 different players in Super Bowls. Joe Montana had 11 career Super Bowl touchdown passes, second in the game’s history behind Brady (13).

The unheralded tend to star

Brady has 101 career touchdown passes to undrafted players, 15 more than he has to first-round picks (86). His undrafted hero this season -- Chris Hogan. Brady's Super Bowl LI counterpart, Falcons quarterback Matt Ryan, has 101 more touchdown passes to former first-rounders (133) than undrafted players (32).

But not just with touchdowns

The Patriots have the most snaps in the NFL by undrafted players over the last decade (nearly 54,000 since 2007). Among them this season, Super Bowl XLIX hero Malcolm Butler, who leads the Patriots in snaps over the last two seasons (1,991).

A light hit

Brady’s average career cap hit is $9.6 million, ranking an average of 17th annually among quarterbacks since 2000 (that is, the bottom half of the league). It ranks 15th even if you don’t count the years on his first NFL contract (2000-01). The active annual cash value of Brady’s current deal ($15 million) is less than Brock Osweiler’s ($18 million).

Trading frenzy

The Patriots have made 62 trades outside of draft day since 2001, including eight since the start of last offseason. Both figures are the most in the NFL. The trade for tight end Martellus Bennett is just one of the Patriots' productive acquisitions from the last year.

Thanks for the help

Of the Patriots' draft picks under Belichick, 78 have been acquired from other teams, most in the NFL since 2000. New England's entire 2012 draft came from picks that were traded.
