Discussions of the NFL adding a developmental league for the many young players, coaches, officials and executives who can't get their foot in the door have picked up steam recently. Troy Vincent, the NFL's head of operations, first mentioned the idea of bringing back a proving grounds for the league to develop young talent in April. According to a report from The Associated Press, enthusiasm for such a project quickly gathered steam. That excitement was quickly endorsed by St. Louis Rams coach Jeff Fisher late last week. "I’m absolutely, 100 percent in favor of something like that, yes," Fisher said. It's no surprise that any coach would approve of the idea of adding a place for young players, coaches and others to gain valuable experience. As it stands, teams only have eight-man practice squads as a method for retaining young players they like and even that doesn't come with any guarantees. Other teams can sign players from practice squads at any time so long as they place them on their active 53-man rosters. Theoretically, a team can invest multiple years in a practice squad player only to see another team poach him after the original team put in the work to bring him along.
