Bama of course usually throttles the Vandys of the world. There also a few times where they don't play well and win by a less than impressive score, maybe 27-17 or so. That's the kind of game where another couple breaks going to wrong way and they end up losing, but that happens rarely, like when Stanford upset USC as a 40+ point dog.
I saw a few plays in the game and I thought the Vandy OL was "managing" the Bama DL a lot better than usual, so perhaps Vandy is toughened up now. If a team dominates in the lines of course, it's much tougher for them to end up losing even if skill players play badly.
I was musing a bit about throwing. I pitch some, still, in baseball, my arm of course is not great. I can throw a curve and have a changeup that is "OK". But, I'm 60.5 feet away, the catcher is still, and nobody is trying to tackle me. A QB is usually leading a moving target with defensive players both trying to get to him and trying to cover the WR. AND, he's often throwing a much larger ball 30-40 yards, not 20. It's amazing to me really that a completed pass isn't like a 10% percentage play. His target area is a bit larger, but not by that much, and missing it can result in a very bad result, not a walk.
