(Signed: Cleveland Browns, March 10)
After starting the first seven games of 2016, center J.C. Tretter lost his job as the Packers' starting center due to a sprained MCL.
Tretter was on an offense line where that rarely allowed Aaron Rodgers to get hit and was a big reason for Eddie Lacy's short-lived bounce back season. Tretter is only 25 years old and could still be a starting center in the NFL if his knee becomes healthy.
