2012 (Wpg:) Buck Pierce began the season as the starting quarterback for the first three games before missing the next eight with a knee injury. After returning to the field on Sep 21/12, he led the team to a 34-12 victory over the Hamilton Tiger-Cats, completing 21 of 31 passes for 288 yards and a touchdown. Pierce showed off his veteran leadership in that game as the offence looked completely different and more confident with him behind centre and he helped the team record their highest time of possession in over six years as they held onto the ball for 37:31. After being knocked out of the game the following week, he would return to start two more before missing the final regular season game with a shoulder injury. Pierce finished the year completing 68 of 113 passes for 951 yards and three touchdowns. He also added 60 rushing yards on 12 carries.
