Most coaches and players will quote a 'next man up' mentality when asked about injuries, adding that it's a part of the game. However, there also comes a time when an injury-riddled team simply runs out of quality players. It's a scenario we saw play out with the New Orleans Saints offense this season.

The Detroit Lions may need a replacement for defensive coordinator Aaron Glenn soon, as the Lions coach is likely to land a head-coaching gig in 2025. With that in mind, one NFL analyst is urging the Lions to replace Glenn with a two-time head coach who has experience as a defensive coordinator.

Now, the Lions are also starting over at both the offensive coordinator and defensive coordinator positions on their coaching staff, with OC Ben Johnson being hired to be the next head coach of the Chicago Bears and DC Aaron Glenn being hired to be the next head coach of the New York Jets.
