The lockout is in response to the union's decertification, but if they did not decertify when they did, they would have had to wait six months to do it.
A lot of people frame this as billionaires vs. millionaires, and say both sides are greedy, but it's only superstar players who makes millions a year. Most players "only" make a couple hundred thousand a year. Yes, that's still a lot, but there's no league without the players.
The NFL with replacement players will be like the XFL and we all know how well that worked out. The XFL's rules and marketing hurt it as well, but you need good players to make a good sport. Look at basketball, it's more popular than ever this season because of the return of powerhouse teams like the Lakers, Celtics, and Heat. How many less Colts fan will there be without Peyton Manning? Probably as drastic a reduction in Bulls fans when Michael Jordan retired.
The league is the players, and these owners simply inherited or bought the hard work of the original owners who were actually taking a risk by investing in the NFL. Nowadays, owning an NFL team is pretty much a golden ticket, and it is so because of the players. The $9billion in TV revenue that they're arguing over, by right should belong to the players. No one turns to the game on Sunday to see the owners sitting in their luxury box. Yes owners build their teams, but they do so by hiring a competent GM and coach to whom they turn over the reigns, except for Jerry Jones and that hasn't really worked too well.
The players give fans hope that their team will win the championship, players are the ones who visit community schools, and tell kids who are getting bullied that they're brave. Yes they're not perfect, no one is, but the I say again that the league exists because of the players, and the players better the community often with just their presence, and more often with much more.
The owner of the Saints may be the one exception as fans down there know his name as readily as they know Reggie Bush and Drew Brees.
