The whole point of replay review is to produce the right call, not overlay some alternate reality to justify a different outcome. Michigan won the game based on the official clock in the stadium witnessed by 110,000 people, not NBC's lagging video feed.
The FBS Oversight Committee said in a statement that instant replay protocols were not followed on the second-to-last play of the Western Michigan-Michigan game.
Had they been followed, the committee says the games outcome would have been different, but the result cannot be changed.
