The Panthers have signed backup guard Keydrick Vincent to a 2-year, $2 million dollar contract.  Vincent has great size at 6’5″, 325 pounds but he’s never really lived up to his ability.  Vincent played in 8 games last season (1 start) for the Cardinals last season.  He has now played in 67 games (49 starts) over his 7-year career.  Vincent will likely only be a backup for the Panthers this season.
