How is it giving your team a ceiling?
What you're talking about is exactly why an option offense would be a great fit. Not that I would want a QB to get hurt, but with this style of offense, it's basically plug-and-play with the next guy up. This is because you aren't expecting a prototypical quarterback to drop back and make reads between linebackers, in the secondary, etc. You're asking him to make a read at the line, run the ball, pitch it, hand it off, etc. So the drop-off from starter to backup for option offenses isn't nearly as big as for teams like us.
Georgia Tech did fine against ACC defenses. They did well several years against Georgia, Tennessee, Mississippi State, several others. I mean, Adrian is getting hurt running whatever crap we're trying now, but we can't go with Smothers because he can't run the offense well enough to be effective.
