Going for it..

According to Len Pasquarelli this morning, more and more NFL head coaches are going for it on 4th down-- and aggressive offensive linemen are loving it, apparently...

It's a regular trend. A phenomenon.
And yet there's not one mention of Charlie Weis in this article. How can that be possible?
I have nothing scientific to back this up, but I'm fairly certain that going for it on 4th and 6 wasn't nearly so popular until sometime last year, after Charlie had done it 8 or 9 times.
