The Olympics has nothing to do with the switch.
The contract with Hawaii was up after last year and the NFL wanted to try a new format.
They felt that it'd be better to have a big celebration in the week between the Conference championships leading into the Super Bowl and they figure it'll get more people to watch the Super Bowl.
However, by not having it in Hawaii, I think it diminishes the appeal to the NFL players and also the fact that A LOT of the highest voted players won't be eligible to play in the game also diminishes the appeal of it. Tom Brady and Big Ben voluntarily dropped it. That's not something you usually saw in the past....
I hope it doesn't kill the game completely.
