Thoughts on the new Overtime rules?

Illinois just beat Penn State in nine overtimes.

It was fun as hell, but it is not sustainable if we are going to get many games like this.

The new overtime rules where you have to go for two as your one-play "drive" after 2 OTs remove too many of the variables that can end the game:  Multiple plays per drive, distance from the goal line, and potential touchdown / extra point / field goal points differential.

Under the new rules those variables are gone by the third OT:  both teams have the same number of plays (one), from the exact same 3-yard distance from the goal line, for the exact same score.

If you have two high-scoring teams, or two low-scoring teams (like today), you can't get them off the field. 

Thoughts on this or a better system?  Or just keep it the way it was?
