Guys are bigger, faster, and stronger than ever before. Every play the forces of impact are like getting hit by a moving car. One thing I’ve long argued the NFL needs is improved roster flexibility. Forget the 53-man roster, 46-man gameday roster, and practice squad. Teams need a 65-man roster with 50-man game day roster. There should also be a shorter term DL instead of IR. If a guy will miss 3 weeks, a team should be able to DL him and add someone else to the roster without ending his season (the rules have gotten better here with 2 guys now able to come off IR). With concussion rules, painkiller abuse, and waiting to properly rehab injuries, the NFL is currently encouraging players to lie about injuries to remain in the lineups. The Packers were among several teams with more guys OUT than inactive spots, resulting in playing a few players shorter than opponents.
