In the first half of Philadelphia's 38-20 loss to New England on Sunday, defensive line coach Jim Washburn and offensive coordinator Marty Mornhinweg got into a heated verbal exchange on the sideline. The exchange happened early, when the Eagles still held a lead. While it was brief, the two had to be separated by sideline personnel. Details of their disagreement were not revealed, but the argument typified the season, which has been all about frustration.
