The brand new Alliance of American Football league makes its debut on Saturday. Former Buffalo Bills general manager Bill Polian helped establish the football project.

The eight-team developmental league will play four games per weekend for each of the next 10 weeks, split over Saturdays and Sundays and aired on CBS, TNT and NFL Network.

Aside from Polian, plenty of other former players and coaches with connections to the Bills are taking part in the new league.

Here are a few names you might recognize if you tune in for this season of AAF:

C Patrick Lewis

During the final roster cuts for the 2016 season, the Bills claimed Lewis off of waivers from the Seahawks. The year prior in 2015, Lewis saw extensive playing time with Seattle, including nine starts but he never really cracked the Bills’ roster. Lewis spent the entire season with the Bills that year, but was only active one game, a Week 13 loss to the Raiders, where he played 17 snaps. That was the season Eric Wood missed the entire second half of the season, but Ryan Groy, not Lewis, saw starting time. The Bills were the last NFL roster he was on. Buffalo released him in July 2017. He’s now a member of the Arizona Hotshots.

WR Kaelin Clay

Clay actually spent two seasons with the Bills. In 2017, the Bills traded for him via a deal with the Carolina Panthers which saw cornerback Kevon Seymour head in other direction. Then he was cut and re-claimed by the Panthers that same season. During the 2018 offseason, he then came back to Buffalo but was cut by the Bills at the end of training camp.

In total, Clay mustered up one catch for 28 yards with the Bills and had two punt returns, one of which he fumbled. Clay is on the Salt Lake Stallions.

CB Ron Brooks

Brooks, a fourth-round pick by the Bills in 2012, went on to play four seasons as a reserve defensive back for Buffalo. Brooks never intercepted a pass during his NFL career, but did have seven passes defended and 62 tackles for the Bills during his four seasons.

After the 2015 seasons which ended on injured reserve, he signed a three-year free agent deal with the Eagles, who also brought in former Bills defensive coordinator Jim Schwartz, who Brooks played under. However, after a right quad injury, he was released the following training camp in 2016. Brooks is a member of the San Diego Fleet.

TE Keith Towbridge

Towbridge spent two seasons with the Bills. He signed with Buffalo as an undrafted rookie in 2017 but spent the season on injured reserve. This past season he was released but re-signed to the practice squad.

Really the thing he’s remembered for is this Instagram post earlier this offseason with the Bills apparently released him:

Towbridge signed with the Atlanta Legends.

DT Rickey Hatley

Prior the Bills’ season finale in 2017, Hatley signed with the Bills’ practice squad on December 23. Then on December 26, he was promoted to the 53-man roster, where he recorded one tackle against the Miami Dolphins in the Bills’ season finale. While his Bills’ career is brief, he was part of the locker room scenes where Bills players watched the Bengals defeat the Ravens to send Buffalo to the postseason. In the playoffs, he also saw 20 snaps against the Jaguars, between defense and special teams. Now Hatley is on the Birmingham Iron.
