The REALLY most important blown call of the game has pretty much been overlooked...the Packers intercepted a pass & they called Roughing the Passer, negating the INT that would have sealed the game for the Packers.
That call wasn't even close, and I told myself after it happened "OH NO". I just KNEW the game would turn on that. I never dreamed like this, however.
Whenever people today see something dramatic like this, they impulsively say "it's the best/worst/greatest in history", regardless of how much they actually *know* about history. So I won't comment on whether this deserves to be in any Top 10 list.
By the way, regarding the missed 2-point conversion...according to Aaron Rogers, the refs gave him a "kicking ball" for that play...the balls especially designed for kicking, which are over-inflated & practically impossible to throw. So even here, the refs showed their incompetence & further influenced the game for the worse.
