The concept of voluntary offseason workouts generates plenty of consternation for football media and fans. Some react angrily whenever anyone points out that a player has chosen to stay away from voluntary sessions. Others believe that all players should volunteer to show up for any and every practice Greg Little Jersey , voluntary or not.For me, it’s a source of constant conflict. On one hand, I support the ability of players to choose not to be there. They’ve earned that right via collective bargaining. Indeed, I’ve argued on many occasions that, if all players were to boycott voluntary offseason drills, the NFL would immediately make a major concession at the bargaining table in order to get them to come back.On the other hand, there’s value in working out with the team. For starters, an injury suffered when a player works out on his own, he has no financial protection. If he blow out an Achilles tendon, he doesn’t have to be paid. Conversely, if he gets injured at the facility Will Grier Jersey , he’s covered.Also, there’s value in building camaraderie, establishing relationships, and participating in a shared sacrifice — especially for players who are new to a team, like Jets running back Le'Veon Bell. He hasn’t participated in any aspect of an offseason program in at least three years; there’s real value in Bell making a statement to his new teammates, new coaches, new media, and new fans that, like most other players on the team, he’s all in.Of course, if the Jets wanted to ensure that he’d be there Christian Miller Jersey , the Jets could have loaded significant workout bonuses and/or salary de-escalators into his deal, creating a financial incentive to show up. They didn’t, and Bell is now exercising his broader contractual rights to not be there.Again, he has that right. At some point, however, it’s about building a team. It will be hard for Bell to be part of that if he’s not there, working alongside a brand new set of teammates. Things have changed a lot within the past five years of the NFL. Teams have made moves that have helped develop the team they have today, but they have also made some questionable decisions. Every team makes a bad decision, and over the course of five years, you’re bound to find a pretty big mistake that each team made. Mistakes happen, they are a part of life Jordan Scarlett Jersey , but they could have impacted a team tremendously.Think about your favorite team and something you wish they never did. Pretend as if that move never happened, how would it affect your favorite team today? For some teams, it wouldn’t be that big of a deal. For other teams, it could mean a lot.Front offices come and go. General managers and other people that are a part of the decision-making process constantly are in and out of offices. And part of that is because some people have different agendas than others. Each team on this list will bring up a scary nightmare that is either ongoing or something that makes you shake your head from the past. Nobody likes hearing about these poor decisions, but sometimes you have to look back at them.We've listed 32 mistakes, one that will affect each and every NFL franchise. Some that are fairly recent, others that go as far back as 2013. So, prepare for the nightmares that hang over your franchise, as we look back at the worst decisions made by each NFL franchise in the past five years.
