The Lions have signed WR Shaun McDonald to a two year contract.  McDonald played for Mike Martz in St. Louis and he likes the speedy receiver.  McDonald played in all 16 games last season and he caught 13 passes for 136 yards (10.5 avg) with 1 TD.  He also returned 23 punts for 172 yards (7.5 avg).  Look for McDonald to have his best season as a Pro as he will likely be the #3 wideout for the Lions this season.
