many great posts by Dinugs, Zero, British.
However, no need to blame refs. Was that a fumble by CM3? Of course, but within about a minute or two, the packers had moved right back to that part of the field with the D.D. reception, and with so much time to go in the game, it had very little impact.
And yes there were dropped balls, crosby sucked, and although I like our defense and the strides they've made, and the steelers played a hell of a game, but the game came down to them stopping the steelers from marching ~80 yards in 2 minutes. A championship caliber football team should expect their defense to rise to that occassion, and they were unable to today. Tons of upside to this defense, but they were the reason the pack lost.
