Go back to Puffed Chest on the playground. He's not someone who wants the Eagles to win and hopes Wentz develops into a superstar. He needs those things to happen. His identity is bound up in their happening. He sees another guy wearing the apparel of another NFL team - a team that has been far more successful over time than the Eagles - and he can't abide it. This is supposed to be an Eagles safe space, and Steelers Guy has invaded it. How dare he. And around here, Puffed Chest is not atypical. Listen to the people who call the talk-radio stations. Read the online comments on any article or blog post about the Eagles. Notice, as the local cliche goes, the difference between the city's collective mood after an Eagles victory and the mood after an Eagles loss. If Wentz goes through growing pains as a new NFL quarterback, how patient do you think Puffed Chest and those like him are going to be?
