There was an article on either Google News or ESPN about the horrible teams this year in the NFL. It is the first time we've had this many winless teams in something like 40+ years. It's a bad look as NFL teams are starting to rebuild the way NBA teams have been doing it for years. It creates an ugly problem; No more parity. The salary cap era was supposed to bring balance to the force, I mean to the NFL. It worked until owners figured out draft picks are easily as valuable as top free agents. We're seeing more players able to force themselves onto the teams they want (like the NBA) and more owners willing to tank as they get their revenue stream from the TV/Cable packages, not the fans attending the games. If you are an owner with stock in your stadium, own the parking garages and concessions, you don't need many fans to attend. Jerry Jones makes more money on his stadium being used for other events, like Concerts and the parking fees, than he does on the NFL games. It's not an issue for him as the Cowboys routinely sell out and are usually at least competitive. An owner of a team like the Dolphins can make a fortune by staying at the salary cap minimum and not having a huge team staff to pay for.
Football is definitely changing. I hope the new CBA rectifies some of this or in a few years, it will resemble the NBA. Only a handful of truly competitive teams and the rest will be marginal. It's why they want to expand the playoffs in the NFL. Let in two more teams, build up more of a following for the exceptionally average teams that make it to the playoffs and not worry about building real dynasties anymore.
