Check out Yahoo! SportsThere's a little known fact when it comes to the history of the National Football League. It's not earth shattering but it is certainly interesting.Starting with 1920 and the birth of what we now refer to as the NFL, there's been at least one team to total at least three championships in each of the league's nine decades of existence.But will that streak of sorts come to an end during the current decade? So far, we have seen the Green Bay Packers (2010), New York Giants (2011) and Baltimore Ravens (2012) capture the first three Super Bowl titles of the 2010s. Are any of these three clubs capable of going on another championship run and make it two or more titles this decade?
