The heated exchange pitting Bret Bielema and Shane Beamer against each other kept social media buzzing on New Year's Day. Illinois won the Citrus Bowl against South Carolina, 21-17, capping a 10-win season.

Illinois' 21-17 win over South Carolina in the Citrus Bowl -- a historic marker for the Fighting Illini, who for the first time since 2001 eclipsed 10 wins in season -- was overshadowed by a bizarre feud between two of college football's most colorful head coaches.

Beamer's anger likely stemmed from a tit-for-tat battle between the two coaches, each of whom were sending in late substitutions all game long. And Bielema's laughter occurred shortly after the heated interaction, when he sent in three defensive players with the play clock winding down, forcing Beamer to burn a timeout.
