This bad call didn't make a difference in the outcome of the game, of course. The Seahawks certainly earned their championship. However, it was a bad call nonetheless. When Russell Wilson was out of the pocket and being chased by defenders, he threw a shuffle pass to no one to avoid a sack. However, the ball didn't get to the line of scrimmage. By rule that's intentional grounding. The announcers were saying that the refs must have thought the ball got close enough. However, that's not the rule. By rule the ball has to get back at least to the line of scrimmage or it's grounding. Flag should have been thrown.
