IMHO, Vandy would have blown WKU out last night with their turnovers. If that game isn't a complete fluke then UK won't win a single SEC game. They will be a 3-9 team at best.
I still could see Vandy having a similar performance after last year. I agree with your main point though. I don't see Kentucky winning a single SEC game, even Vandy, with the way their line played on both side of the ball. I didn't see anyone or any group that could being to replace Cobb's production. And they were getting out coached on top of that.
