Pretty easy to second guess and assume he meant that he should have sent in a pass play. And it is way easier to sit on a couch and yell like you know what would have worked than to get the down and distance, decide on a play, and send it in while all that commotion is going on around you. Oh.... and do it in about 10 seconds so your team can run the play. Did we take a time out there? I don't recall.
Regardless, he is saying this now in hind sight. He's seeing things that would have worked in that situation. This is a staff that will admit when they missed something because they intend to make adjustments from minute to minute during the game and from week to week in between.
This is also why I really believe that he will have a winning game plan against the shecocks and that this team will continue to get better as the season rolls on.
