I had mentioned in another thread(Show me your Chicago Bears stuff) how The Bears loss this year to the Bengals was the worst i'd ever endured in my 25 years as a fan. I'd seen the lose by a higher margin before, and in much bigger games. It was just the way they lost, and how overmatched or lack of effort once they were down that made it the worst. So my question to you is:

What's the worst loss you've seen your favorite NFL team endure? Not Necessarily the largest point margin, or the biggest game. Just the one that your team really looked their worst.
