A litany of startup football leagues has tried—and failed—to become rivals to the mighty NFL. A new contender plans to try something different: It aspires to be an alternative to college football.

Don Yee, better known as Tom Brady’s agent, is launching a professional football league that will target young players who don’t qualify for college or just want to make money sooner rather than later. In limiting the player pool to those between 18 and 22 years old, the venture will challenge a nearly century-old system in which the National Football League relies almost entirely on colleges to prepare its future workforce.

“It’s a good time to start a development league and give players a choice and an option to consider other than the well-worn path to professional football,” said Yee.

The Pacific Pro Football league will debut with four teams in 2018, Yee said, and features an advisory board with prominent former NFL figures such as Mike Shanahan.

Though Yee is closely identified with Brady, who controversially missed the first four games this season due to his “Deflategate” suspension, the New England Patriots quarterback isn’t involved in the new venture.
