The Ronnie Harmon drop against the Browns in the playoffs might be my #2. Illegal Forward Pass was the most infuriating loss, but as far as heart breaks go, in the moment I was more heart broken when we lost in the Dawg Pound. Long term, the Music City Miracle is more devastating bc that was literally the last gasp of the that era's Bills and it's taken 20 years to start feeling like it used to.
