Yea, but what Quaors and Hump are saying is that statistically, it actually puts you at a disadvantage to call a timeout to try to "ice" a kicker. Check out this quote from the WSJ:
"Since 2000, NFL kickers made 77.3% of field goals in the final two minutes or overtime when no timeout was called before the kick. But when a timeout was called, kickers made 79.7% of these field goals, no matter the distance."
Here's the whole article: http://online.wsj.com/article/SB10001424052748704129204575506112194098670.html
And numbers that go back further back this up, too. Icing the kicker, statistically, does not work. Period.
