T.J. Lang signed with the Detroit Lions on Sunday, ending his eight-year relationship with the Green Bay Packers. On Monday, Aaron Rodgers, his now former quarterback, took to Twitter to share some thoughts on Lang.

Rodgers has been busy on Twitter during this free agency period. On Friday, Rodgers responded to his Packers signing Martellus Bennett with an upbeat tweet. Obviously, this one is a little more somber in nature.

Replacing Lang will not be an easy task for Green Bay. A line that often struggled through the 2016 season now heads into 2017 with one of its Pro Bowlers on a division rival.
