The SEC has had an anti-field storming policy and fine structure for many years, and I always suspected their fans were a little jealous when they'd see BTen fans storming fields with no repercussions. I was amazed that they were so obedient and never stormed their fields...until a few years ago. Then one team's fans broke the ice, then it started happening a little more often, so this year the SEC upped the anty.
The conference used to have a graduated policy of fining the school $100,000 for the 1st offense up to $500,000 for 3rd offense and beyond. But starting with this season it's a cool $500,000 fine -- paid directly to the opposing school (!) -- for ANY offense of fans storming the field. Would've liked to have seen Dion's face if the B12 had THAT penalty!
