The Cleveland Browns hold the record for best team by wins, championships than any other current NFL team. Although the NFL changed the championship game name to Super Bowl, the Browns have won more titles than any current team to this day in 2012 and have more game wins than any other team as well, making them the best team ever. Bryan Pressley is a band wagon Steelers fan.
