The College Football Playoff is finally here.

Clemson vs. Oklahoma at the Orange Bowl and Alabama vs. Michigan State at the Cotton Bowl make up the two games on New Years Eve.

If you have been watching College Football this year you probably know the usual suspects with each of the top four teams but here are four facts that you may of not known about Clemson, Oklahoma, Michigan State and Alabama.

Clemson - It is no coincidence that Auburn and Clemson share the same team mascot. Walter Merritt Riggs is described as the "Father of Clemson Football," as he brought the game with him from Agricultural and Mechanical College of Alabama which is now Auburn University.  He then allowed his players to pick the team mascot and although he may have tried to influence the final decision by the players, they ended up choosing Tigers because Princeton University had just won the national championship. Riggs helped organize and coach the first Tiger team in 1896.

Oklahoma - As great as Bob Stoops has been at Oklahoma, Barry Switzer was even better.  The former OU player turned head coach won three national titles with the Sooners in 1974, 1975 and 1985.

Alabama - One of the most legendary coaches in College Sports history, Paul "Bear" Bryant spent 24 years as the head coach of Alabama.  In today's coaching world, that is an eternity. Now we've seen some long tenures from guys like Joe Paterno and Bobby Bowden, but Bryant certainly deserves to be in that conversation about longevity at one school.

Michigan State - In 1953, Michigan State won its first Big 10 conference championship.  Since then, they have won 8 more conference titles in the Big 10 including three since 2010.
