The Kansas City Chiefs and Philadelphia Eagles sure looked like the two best teams in the NFL, and they delivered an excellent Super Bowl despite playing on a sorry excuse for a field. In the end we saw the Chiefs pull off their second championship win in four seasons, which is as close as you can get to saying we might have our first non-New England Patriots dynasty of the 21st century NFL.
Perhaps the Seattle Seahawks were the dynasty that never was. They stormed their way into a title, came within a yard of a second, and have not been particularly close since then.
