Richard Sherman Apologizes for Post-Game Rant; Was Shocked by Racist Response

Richard Sherman: Rant was 'immature,' reaction 'mind-boggling' (CNN)

There are two Richard Shermans.

There's the smart Stanford graduate who loves to read. And there's the brash, trash-talker who considers himself the best NFL player.

One is quiet, reflective. The other can be loud -- very loud.

Much of America met the second Richard Sherman on Sunday night when, after making an amazing defensive play to seal the Seattle Seahawks' trip to the Super Bowl, he ranted in a postgame interview about his opponent.

On Tuesday, we caught a glimpse of the first when Sherman showed up for a sit-down with CNN's Rachel Nichols for a mea culpa -- but not for long.
