Mine would probably be different. Most might say the Browns. I was honestly never sold on them so, IMO, they didn't disappoint. But based on the expectation they generally had, I guess they would be.
From my perspective, I would say the Chargers. It seemed like they were too good overall not to make the playoffs.
I might also say the Ravens but they were maybe the most snake-bitten team due to injuries. Quite frankly, I thought they actually did pretty well given the injuries they had to endure as well as the brutal schedule they had to go up against.
