Offensive coordinator Frank Reich said Wentz "seemed totally unflappable" earlier this season, but the coach sensed that Wentz has been feeling the losses in recent weeks. The Eagles have lost three straight games and seven of their last nine. Reich said that Wentz arrived young and naive "in a good sense," and is now learning how to deal with losing - just as almost every quarterback in the NFL has needed to do. Wentz called the losing "frustrating," but he insisted that he cannot waver.
