Murray didn't play badly. He went 24-for-37 passing for 285 yards but did not have a touchdown and was intercepted. That interception was returned 69 yards for a touchdown.
But he had a few crucial mistakes. One of them was interception. It was a four-on-one game. Murray wanted to run outside to get the first down. However, Seahawks cornerback Devon Witherspoon stuck with him and tried to keep him from taking the No. 1 spot. Murray, who had Michael Wilson in the penalty area as a potential target to save himself, tried to throw the ball to him. The throw went completely wrong, Coby Bryant caught it and scored.
It wasn't a bad decision. It was a great play by Witherspoon, and if Murray had accurately thrown it to Wilson, it would have been lauded as a great play, much like Patrick Mahomes regularly seems to do.
The other glaring mistake was when Murray, on third-and-goal from four, left McBride open in the end zone and simply threw the ball too high, resulting in a field goal. Had he scored on McBride, they would have trailed 13-10 with 10:08 left.
