News out of Chicago is that DT Darwin Walker returned to Bears practice yesterday and could very likely suit up against the Eagles on Sunday. When they traded him away this off-season for Takeo Spikes and Kelly Holcomb, the Eagles must have been circling that December 30th matchup with the Bills on their calendars and worrying about the wrath of the displaced tackle. But a cruel twist of fate has landed Walker in Chicago, and now the Eagles will have to gameplan for the immovable object on the Bears' D-Line. No word yet from Reid and company on how they'll get past this obstacle, but they may try the only plan that seemed to work for Eagles opponents last season: run right at him. Survival of the fittest. It's so crazy, yet so simple, it might just work.
