Obviously you don't either, because your .80 payout means your balls are on a test cycle with no HCG.
"Normal" NFL odds with a spread:
91/100 for X,Y
95/100 for X, 87/100 for Y
You would have attracted more bets without that 8/10 payout. Hell, even I would have placed a bet. I kindly suggest you change the odds and make them legit, unless you don't have the balls to do so.
If you don't, I will personally post a 75,000 limit with legit odds tomorrow morning, just to show you how big the real bookie's balls are.
