Just an outsider's opinion, but your QB hasn't been your weakest spot on offense. Until you shore up your OLine, it won't matter what QB you throw under center.
Ehlinger is a very good college QB. Decent to good arm, and is really good at short yardage rushing. Stopping Texas on 3rd and 3 or less is a DC's nightmare. But your OLine has holes. Or better yet creates holes where none should be.
You guys have a salty defense when everyone's not injured. You're not where BJ Foster thinks you are (those comments were just silly), but you had one of the best DB recruiting seasons ever just two years ago. You guys were just really beat up or injured most of the season. It'll be interesting o see where Ash can get you to.
Anyhoo, like I said, you'll definitely need your QBs to pan out (all teams do), but to me, you guys need to hire the best OLine coach you can and whip them into shape. THAT's where it needs to come together.
Just my .02 cents.
