RENTON, Wash. -- Seattle Seahawks cornerback Richard Sherman said in a column for that he's not a villainous person.

Sherman has been a regular writer for for most of the season. He wrote on Monday that his postgame interview Sunday with Fox reporter Erin Andrews stemmed from adrenaline and his dislike for San Francisco wide receiver Michael Crabtree. Sherman screamed during the interview that Crabtree is a subpar receiver.

Sherman wrote, "It was loud, it was in the moment, and it was just a small part of the person I am."

After the game Sherman didn't back down, calling Crabtree "mediocre." Sherman wrote that his personal problem with Crabtree stems from an incident during the offseason in Arizona but he didn't elaborate.
