Dan Quinn, defensive coordinator of the Seattle Seahawks, believes Richard Sherman is one of the most astute players in the NFL.

"He's got extreme recall," Quinn said. "Formations, plays and information from this game, last season, last week. And he can recall it fast.

"My first experience with that was when we were getting ready to play Carolina in the opener, and he said, 'Last year, this, this and this.' Without even getting into the game plan that week, he had some formations and alerts that he remembered already."

Sherman almost obsessively watches film to prepare for games.
