That's a classic oversimplification from someone who doesn't watch Vanderbilt closely. Turnover margin is a symptom, not the cause. The real issue is an offensive line that allowed 39 sacks, which puts them in the bottom 15 nationally. Any quarterback is going to make mistakes when they're constantly under duress. Their defense also generated only 12 takeaways all last season, ranking 124th in the country. You can't win the turnover battle when your defense can't get the ball. Fixing the trenches and finding a pass rush is the actual key. Until they improve a run defense that gave up 5.1 yards per carry, they'll be playing from behind and forcing throws, which leads to more turnovers. It all starts up front, not with who's taking the snaps.
