Here's why I feel the timeout is the worst idea on earth.
-If you do call a timeout than the kicker has no worries (besides the win) he can line up and just kick. He also gets a practice.
-If you don't it's in the back of the kickers head that you might and it distacts him, and more importantly...HE DOESN'T GET A PRACTICE KICK!
There is no plus to the timeout.
