Hey, here's a thing about football and offensive linemen and how teammates treat each other that will actually make you feel good, for once.

Panthers left tackle Jordan Gross announced his retirement during a news conference at the team's facility this morning. The press conference was briefly interrupted by Gross' offensive line mate Ryan Kalil, who along with a few members of the Panthers' staff serenaded Gross with a classic barbershop quartet performance. See, football players can be nice to each other!
