I think it was against AFA. Bosco threw a deep ball down the middle. Kozlowski ran across the field from left to right and left his feet to catch the ball. Right before the ball would have ended up in Kozlowski's hands, David Mills cut in front of it going toward the end zone at full speed and snatched it out of the air.
It was one of my favorite plays of the year.

I never heard a surely serious report from Bosco regarding who the intended receiver was, although he did say "David Mills all the way" with a smile once when asked about it after the season was finished.
