I predicted a loss (see the Fearless Prediction thread for proof), so I expected it.
However, at the end of the game it looked like the Seahawks were going to win. They had all the momentum after Cary Williams' TD and were up by 7 with time for the Rams to only put together one more drive. So at that point, I thought the Seahawks were going to win.
Then the hope was ripped away when Bailey fell down to give the Rams an easy TD and then again when Marshawn was stuffed. So the disappointment comes not from expecting the Seahawks to lose, but the fact that at the end of the game I thought they had it won and they found a way to blow it.
