From where I sit it's really simple. The "O" line is completely broken. The expectation at the outset was that the young line would have some troubles but would improve throughout the season. In contradiction to what would normally be expected, the O line is regressing by being poorly coached and lost. Guys are completely missing key assignments every other play. When they do get the assignment correct, they are getting over-matched physically. It's tough to win when the line of scrimmage is so weak.
I don't legitimately see another SEC win on our schedule barring a fluke, and even Liberty will be a challenge if they scheme to attack this weakness. 5 and 7 is our likely destiny. I'm not mad about it (sure it's disappointing) but that's my reading of the tea leaves.
