While parts of this are true and Arkansas was way over-ranked at #3, the offense struggled mightily in that game and only performed well after the special teams and defense made plays.
If by struggled mightily you mean had to punt twice, a fluke fumble and then to start the 2nd quarter they started domination where they put points on the board 6/7 drives (in that other drive there was an INT after 10 plays 68 yards) I guess they struggled.
Also I guess where you missed that 3/3 regular season JJ starts resulted in the 3/4 games that topped 450 all season.
By the way the offense needed a spark from the d and ST all season. Just look at the oregon game for crying out loud. There were only 2 defenses that could stop the run UGA and Bama. Both qbs got a shot against Bama and neither performed well. Unfortunately only one got a shot vs UGA. Just because we sucked on O the last two games (against the only two legit defenses) doesnt mean Miles made the wrong decision to go with JJ (though I was on record saying I wanted to start JL because I thought we were better with both not just one). The last three regular season games have facts that prove that at the very least the difference was negligible.
