I hope you have a great time in my league, and enjoy the sport that first introduced me to competitive football. I was always too big to play tackle football, so up until high school I could only play flag football. It was there that I developed the fundamentals that helped me to capture a high school C.I.F championship, two NCAA championships, and a Heisman trophy.

Have fun out there!

The Matt Leinart Flag Football League, in conjunction with the NFL Flag Football program, is a flag football league for kids in grades K-8th, with the emphasis on community fun. The league is for both boys and girls of all skill levels and promotes a competitive, confidence-building, non-contact football experience. Founded in Newport Beach in 2010, the goal of the league is to provide a fun league for kids to be involved in, while also developing and furthering their football skills.

Games are run on Friday nights in both the Fall and Spring at locations in Costa Mesa, Irvine, Newport Beach, and San Juan Capistrano.
