Why are so many NFL games ending in blowouts?

[BigBusiness]

It hasn't always been like this. A lot of games would come down to the wire in the past. Now everywhere you turn, there's a blowout.

Prime time monday night. After a hard days work, I get home ready for a good competitive hard fought match and it's another lopsided victory. Sunday night football last night and now this. Booooooooorrrrrrrrriiiiiing.

what's the deal?
