Looking for some mention of his 2016 performance but not finding much. Here is what titaninsider.com says:
The McCourty twins will turn 30 in August.At cornerback, the biggest decision may come with veteran Jason McCourty, who still performed well at times, but ended the season with a shoulder injury. McCourty is a team leader, but is also due $7 million next season and will have to fight to retain his starting spot if he is not released as a cap cut. McCourty has said he is open to reducing his salary to stay, if need be.
