From Michael Cohen of the Milwaukee Journal Sentinel:
Center JC Tretter has a large free-agent market and is expected to receive offers more lucrative than the Green Bay Packers will match, according to a source close to the situation, paving the way for his exit from the team that drafted him.
Ted Thompson rarely lets a talented draft pick walk after their rookie contract. But Tretter’s situation is far more nuanced than most.
First of all, he’s only started ten games in his career: three in 2015, and seven last year. Second, injuries have forced him to miss 33 games in just four seasons, according to Michael Rodney of PackersNotes.
