Seattle's last play was Russell Wilson's fault, not Pete Carroll's
But he weakly takes his 2.5-step drop, throws the ball off his back foot and sails it high, right to Butler. If that ball is low and around Lockette’s hip, there’s no chance of an interception. Wilson did everything wrong on that play. Had he received the shotgun, stood tall and whipped the ball to Lockette, Seattle would be planning a Super Bowl parade today.
A better throw probably doesn't result in a touchdown. It may even have resulted in an incompletion, or a tipped pass and interception. But with Wilson's muddy drop and back-foot toss, he deserves a good deal of the blame for the outcome.
