look not further that the following from http://en.wikipedia.org/wiki/2014_Pro_BowlRule changes for the 2014 Pro Bowl:
Two former players, Jerry Rice and Deion Sanders, will draft players on to the teams. As a result, the Pro Bowl will no longer be AFC vs. NFC.
A two-minute warning will be added to the first and third quarters, and the ball will switch hands after every quarter.
There will be no kickoffs. A coin toss will determine which team is awarded possession first, and the ball will be placed on the 25-yard line at the start of each quarter and after scoring plays.
The rosters will now consist of 44 players per squad, with an additional defensive back added.
The defense will be permitted to play “cover two” and “press” coverage. In the previous years, only the “man” coverage was permitted, except for goal line situations.
Beginning at the two-minute mark of every quarter, if the offense does not gain at least one yard, the clock will stop as if the play were an incomplete pass.
A 35-second and 25-second play clock will be used instead of the usual 40-second and 25-second clock.
The game clock will not stop on quarterback sacks outside of the final 2 minutes of regulation/4th overtime.
Tackling is prohibited above the shoulders and below the knees.
Oh the humanity... 
the humanity!
What the hell... 
is going on here?
