Scoring more points and giving up more points.
JG would actually make a great Air Raid QB. He'd fit into Leach's system very well. The O-line would still be an issue, but we wouldn't be banging our heads against the wall trying to run for 3.0 yards per carry. (And that's the 2nd biggest reason we lost behind "not being able to stop GA State's run).
Defense would be in even worse shape than it is right now. I think Leach could get a top-notch DC, but it would still take a few years to rebuild the roster. Frankly, a lot of the problems we saw out there are the result of Butch's terrible recruiting for the D-line in his last few years. After Kyle Phillips and Shy Tuttle graduated, we just had a big dropoff. Our guys were gassed the entire 2nd half.
That said, I think Leach wins this particular game with some crazy score like 59-45.
As much as everyone wants to hate on Pruitt, and perhaps rightfully so, I still think it's too early to tell. So many true Freshman were out on the field in key positions. We saw Wanya Morris make some major mistakes. He's an elite 5-star talent, but there's a reason you don't see Bama playing many true Freshman at O-line. I'll be more worried if I don't see progress as the season goes along. And ultimately, this loss is not really any worse than Saban's Louisiana-Monroe loss back in 2007; another middling Sun Belt team. But it will be if we lose more like this.
