Eagles tight end Brent Celek, a five-year veteran, is embarrassed by the team's play this season. Philadelphia is 4-8 after a big offseason that saw them enter the season with title aspirations. "We've got a lot of talent, and we're just not living up to it. I'm embarrassed about it. I'm sick about it," Celek said. "We've got four games left to prove that we're a legitimate team, because right now the world's laughing at us."
