METAIRIE, La. (AP) — The New Orleans Saints' dead-last defense won't be getting an overhaul under new coordinator Dennis Allen, who says it's too late in the season for major changes. Allen, who took over when Rob Ryan was fired last week, expressed hope that incremental improvements would slow opponents down enough that they won't be able to keep pace with New Orleans' second-ranked offense. "It's not like you can just go in and just wholeheartedly change everything you've been doing schematically," said Allen, who will debut in his new role Sunday in Houston.
