His passing has been top of the charts this season as well, throwing 1,409 yards for 14 touchdowns with four interceptions.Pavia has completed 71.4% of his passes in the first six games of the season but he was limited to a 60% passing completion rate in Vanderbilt's 30-14 loss to Alabama on Week 6.LSU will counter with senior quarterback and early Heisman Trophy favorite Garrett Nussmeier, who has thrown for 1,413 yards with nine touchdowns and five interceptions this season.Nussmeier didn't have his excellent stuff in LSU's 20-10 win over South Carolina. He passed 254 yards with two touchdowns and two interceptions and completed 60.6% of his passes against the Gamecocks.
