The ball will change hands at the end of each quarter, which could double the opportunities for two-minute drills. Kickoffs (and return specialists) will be eliminated - teams will start on their own 25-yard line. Defenses will be allowed to play cover-2 and press coverage in addition to man, and several clock tweaks have been instituted to speed up the game and prompt offensive play.
Why don't they turn this into a flag football game played on the Saturday before the Super Bowl at the Super Bowl location? Put mics on all of the players and maybe it could be interesting to watch.
Nobody cares about the Pro Bowl so no need to try and make it look like a real football game when it is not.
Advertisers care, because regardless of how bad the game is, people are still watching. This year's pro bowl had better ratings than any of the other major sports all star games, and it had a better average rating than the World Series.
CBS declined to show the game this year, I think that is twice now they have done that when they had the rights to the game. I would have to think the only reason they would do that is because it doesn't make much money.
