I don't know, breh. It was enjoyable just watching both teams prevail.
For the Broncos, they were facing a team that had only lost one game all year and had the MVP of the league. Everybody kept bringing up how they got blown out by Seattle a few years ago and how they hadn't fared too well against black QBs in SBs. Not to mention they had an old PFM who could barely throw the ball.
For the Cavs, they were facing a team that just broke the regular season wins record and had the MVP of the league. Nobody was really giving them a chance because this was supposedly the greatest team of all time who had just beaten them in last year's finals. Not to mention the 50-year championship drought that hung over the city.
Denver's victory was surprising because of how dominant the defense was. Brehs knew they were good but I don' think anyone anticipated them being so good that they could single-handedly win the damn game.
Cleveland's victory was surprising because they came back from being down 1-3. It had never been done before. They had to win two on GSW's floor, too, which seemed like a hugely daunting prospect.
