The most prolific quarterback in UNC football history is now a Cheesehead.

It was announced late Thursday afternoon that Marquise Williams, who went undrafted in April’s NFL Draft, was signed to a rookie contract by the Green Bay Packers.

The Charlotte native also had a tryout with the Packers’ division rival–the Minnesota Vikings–earlier this month before eventually ending up in Wisconsin.

Now the fourth quarterback on Green Bay’s roster, Williams will compete with former UCLA star Brett Hundley and fellow rookie Joe Callahan–last season’s Division III Player of the Year at Wesley College.

Each man will battle during training camp to be the backup to Aaron Rodgers, with at least one of them likely to be cut during the preseason.

Williams also leaves behind a legacy that still may loom over Kenan Stadium in the fall.

Junior Mitch Trubisky will take control of the Tar Heel offense after two years studying under Williams–and at times taking over for him whenever he was struggling, or if his helmet was knocked off by a defender.

A highly talented player in his own right, Trubisky will still have some large shoes to fill.

Over the course of his career in Chapel Hill, Williams played in 48 games–starting in 33 of them. He also set or tied more than 20 school records at the helm of head coach Larry Fedora’s spread offense.

No Tar Heel signal caller has ever run for as many yards (2,458) or touchdowns (35) as the 23-year-old Williams.

Clemson’s Tajh Boyd (2010-2013) and NC State’s Philip Rivers (2000-2003) are the only ACC quarterbacks to have tallied more than Williams’ 99 career touchdowns–when factoring in passing, rushing and receiving scores.

That versatility helped the Tar Heels become one of the nation’s premier offensive forces over the past couple seasons, as he capped his career in 2015 by leading UNC to its first ACC Coastal Division Championship en route to a school-record 11 wins.
