Andy Reid won't replace Juan Castillo as the defensive coordinator of the Eagles. Reid, explaining why it took him until the end of January to address the 2011 season, said he wanted to take some time to reflect on all aspects of his team after a disappointing 8-8 record. "Bottom line, we have to get better," he said. Reid said he didn't want to make excuses for the 2011 season, but "I'm very optimistic going forward."
