The best tonic for handling Saturday's game with Vandy is to just go ahead and prepare yourself for the very real possibility that Tennessee comes out flat, Milton is overthrowing receivers, and Vandy plays like it's the Super Bowl and we lose by multiple touchdowns. Go ahead and soak in that thought and prepare yourself to witness it, emotionally/physically, etc.
If the end result is better than that, be excited and thank the coaches - because that will be different response than what we've seen the past ~15 years.
