The College Football Playoff Committee picked the four semifinalists Sunday.

Clemson, Oklahoma, Georgia and Alabama all made the top four. No. 1 Clemson will meet No. 4 Alabama in the Allstate Sugar Bowl, and No. 2 Oklahoma will play No. 3 Georgia in the Rose Bowl Game.

Twitter immediately erupted with fans discussing two SEC teams in the College Football Playoff, Alabama making the playoff without a conference championship, and the rankings.
