Ask any professional gambler what they think about NFL officiating, in general.
You've got to get past the Grand conspiracy theory part. It's not scripted, where everyone knows the outcome, but a well placed, back-breaking call or 2 is sometimes all that is necessary.
I never questioned anything until the tuck rule. Then the 2005-2006 AFC Championship game (Colts-Steelers) and Super Bowl that followed. (XL) - that was just a sloppy 2 weeks for the NFL.
Win, lose or draw, the NFL shares the bulk of its revenue. There was actually a time, not long ago, where Walt Coleman was 11-1 against the spread when his crew worked Pats games.
