Coan may have had those TD passes, the one to Mayer was thrown behind him. It took a great play by Mayer to catch the ball. There were a couple throws that were deep with no one close. The pick he threw in the 4th quarter is inexcusable. On a few incompletions, especially on out routes or digs, he threw late instead of leading them. I said it early in the season, he cannot throw a guy open.
OK State had a solid front against the run, but Coan is not a zone read QB. He made several bad reads. There was one in particular on a 3rd and 2, outside guy crashes down the line hard, but he gives any way. That is a keep read all day.
