The biggest example of the difference in perception between Tennessee and Kentucky is that when Kentucky loses a close game it's viewed as a positive. Their coach is doing a great job (even while fielding a punt return unit with 8 players and running the ball with no timeouts and 50 seconds left to play while trailing by 3 points) and they are up and coming. When Tennessee loses a close game it's because they choked and it's terrible coaching.
Btw, Barnett was much more of a factor against Georgia and finally recorded a sack. I'm not sure what his problem has been to this point but the pass rush should be fine. Georgia's offense accounted for only 17 points.
