A week after the Super Bowl LIII confetti falls, the Alliance of American Football will take the field for its opening drive.

Co-founded by producer Charlie Ebersol and Pro Football Hall of Fame inductee Bill Polian, the AAF consists of eight teams and is slated to begin its inaugural 10-week season on Feb. 9, 2019.

On the executive side of the Alliance reside the likes of Troy Polamalu, Hines Ward, Jared Allen, J.K. McKay and Tom Veit. And on the coaching side, there’s the likes of Brad Childress, Mike Singletary, Steve Spurrier, Rick Neuheisel, Dennis Erickson, Mike Riley, Mike Martz and Tim Lewis.

And then there are the rosters.

Each got a slight reshuffle with Tuesday night’s protect-or-pick quarterback draft. Each stands in the ballpark of 50 as the days until kickoff count down.

A long list of NFL notables can be found within them. A long list of players from near and distant New England Patriots past can be, too.

Based on AAF.com’s latest update of assignments, between the Arizona Hotshots, Atlanta Legends, Birmingham Iron, Memphis Express, Orlando Apollos, San Antonio Commanders, Salt Lake Stallions and San Diego Fleet, there are 21 players who’ve previously been in Foxborough.

Here’s a glance through.
