Ok here is the big question. WHY? This game had already been put into the rotten timeslot for a playoff game, neirther team is considered a big draw ratings wise and if any player was trying to fix the game it would be caught, the DB in question might not be back next year due to a bad game, it happens, would you risk a Pro Football career to try and make some side money, which you would likely get caught getting (there is a reason it used to happen but has died out.). If the NFL is the ones supposedly fixing the game then they sure blew it last Saturday when they had two total blowouts that sucked the life out of the games ratings, and they definatly blew the chance at a all New York SuperBowl (last year when it would of meant big ratings with all the 911 stuff in New York although this year it would of been big too). The big fact to put on it all is that if it was one or a few players then they are committing career suicide and probably blowing any chance to ever get anywhere with anything Football related ever again, if it is the NFL then they are gambling on compleatly destroying the game forever (who would watch the game if they thought it was fixed, this isn't the WWE.) not to mention they have really blown it ratings wise in the last couple of Super Bowls. You have to remember that there is just too much on the line anymore to try something like this, 50 years ago the players didn't make squat so they were willing to try to make a few bucks on the side, who would blow a career making millions of dollars a year to pick up a couple of grand gambling. Not to mention why would the NFL risk Billions of dollars a year just to gain a few tenths of a point ratings wise. Not every NFL game is exciting, playoffs or not, besides if the NFL was fixing the games why would they completely ruin their ticket sales for teams like the Bengals and the Lions.
I think it was just the case of a player blowing it in the big game, it happens all the time, they make one big mistake and then try too hard to make up for it and keep making worse mistakes. You also have to remember that this was a very tired Steelers team, when you get that worn out at the end of a game mistkes happen.
