Well, you have below avg pa/bh for a BCS team, and yes, forcing the ball into certain players will increase their TO's. Looking at your team, overall talent and distro, the fact that you're turning the ball over a decent amount isn't hugely surprising.
And then there's the strategic element to it. You've made some decisions in many of your high TO games that have led directly to that result (i.e. running uptempo and/or running plays smack into the teeth of the defense when playing against good press teams). A good example: You have a pg with 91 pe, yet you keep trying to force him to drive against strong press teams and he keeps turning it over, and you haven't made an adjustment.
