No, you are not alone. The radio announcers said the same thing. Two things about that play: (1) Allen definitely made a poor throw, and (2) Zay ran his route 5-6 yards past the first down marker before making his curl. Perhaps that was by design or perhaps he ran a bad route. However, Zay had made his curl before Allen uncorked the ball, so Allen could have made a better throw. That said, if Zay doesn't extend his route so deep, he would have been in much better position to catch the ball. Bottom line though, Allen just missed the throw and he knows it.
