Mine is Browns @ Broncos in 2018. It was Baker Mayfield's first year as a starter and the Browns were still in the playoff hunt in December for the first time in ages. The Browns also hadn't won in Denver in 30 years. There was a ton of excitement around the team and Browns fans took over the stadium. It came down to a sack on 4th down and when the Browns won the stadium went nuts. I'll never forget that one.
