I don't like when a quarterback's interception numbers are used with no context to criticize that player.
It's too simple. Not all interceptions are the quarterback's fault. And it doesn't take into consideration that just like how the offense can beat the defense with scheme and execution for a long touchdown, the defense wins sometimes too. There are fantastic coordinators in the NFL who design brilliant defenses that can confuse even the best offensive players. When you go back and watch film of a game, or even as you watch live, try to figure out if and how the defense may have just won on the play.
