No, you don't pull a young QB because of poor play UNLESS it is clearly impacting the ability of the team to win. The kid from Nebraska, even though having 5 TO's, you could say that 3 of those were simply Purdue making damn good plays and not much he could do about it (outside of the diving INT by Brown..that was a bad decision but Brown made a hell of a play). Unless you are looking at a game like Appleby had against Marshall or VT where his play is clearly the reason for why the team didn't win or isn't going to win, then you make a change. You can't shake a young kids confidence and make him start looking over his shoulder. Unless Hazell wins out, they aren't making a bowl game so you need to build the foundation for next season...and that starts with David Blough (and to a lesser extent Elijah Sindelar)
