Part of me thought and still thinks that deflategate was somewhat of a publicity stunt. It got people fired up and talking about the Superbowl.
As far as the last pass, there's been lots of explanation as to why throwing was a good idea (barring a crystal ball). But even if you think it was a bad idea, explain to me how the outcome of the last play affects ratings or money. Everyone who was going to watch the game already watched it. People who didn't watch it still didn't watch it. Literally nothing changes in terms of ratings based on the outcome of that pass. Doesn't matter if it's intercepted, caught for a TD, or dropped.
The pass probably did get more people talking about the game afterwards, but that doesn't matter much to the NFL. It's not like it will increase ratings for next year much.
It was a good game that was interesting to watch. But if you think the Superbowl is somehow rigged to be interesting, you should watch last year. Lots of Superbowls have been blowouts.
