Ha! Try being from Cleveland! Surely you remember the play "Red Right 88", in the final moments of the 1981 playoff game, Raiders vs. Browns. It was frigid for that game, the Raiders had a 14-12 lead. Brian Sipe threw an interception in the endzone and the Raiders won, and also won the Super Bowl that year. There was criticism that Cleveland should have gone for the field goal (they were inside the 15 yard line at the time). But their kicker, Don Cockroft, was having a horrible game (missed a couple of field goals and an extra point), plus the weather was brutal.
I still recall that entire season, people were talking about the Browns going to the "Siper" Bowl!! LOL!
But I still think the most painful playoff losses were "The Drive" and "The Fumble" against Denver (in 1987 and 1988), when Cleveland had an awesome team (and one of the favorites for the Super Bowl). I was actually at the playoff game in Cleveland right before the infamous "Drive" game, when the Browns came back to beat the Jets in OT to advance to the AFC finals. First NFL game I ever attended, and it was quite cold out! A friend of mine and I got up at 4AM the first day tickets went on sale days before that game, went downtown to the stadium, and waited in line! Bleacher seats, of course (the old Dawg Pound at the old Municipal Stadium).
