I was thinking about Kuhnel last night. The crooked hat, the garbage man physique, the hint of confusion in his eyes.. He has a little bit of a John Rocker aura to him.
I think if he purposely sailed a 98 mph seed to the backstop every other appearance and then looked at his hand like he wasn't quite sure what happened... I think it would make him fractionally more effective. Just give the hitters a fragrance of doubt that he entirely knows what he is doing :)
