I'd have to re-listen to Woody's quote to be sure... But I took the 15% comment to be referring to the fanatical Fire-Idzik website people--i.e., the ones paying money to raise billboards, printing towels and flying toy planes over practice fields. I don't think he meant to suggest that the more reasonable fan who happened to want Idzik fired was in that group. Just my interpretation though.
Chik-fil-a is closed on Sunday's. 1/7 of their market ignored. That's 14%. They've been doing pretty well so far.
