I can understand Kraft's mindset of thinking of prioritizing the welfare of the entire league over the welfare of one team. The problem with that line of thinking is, if everyone else isn't operating based on the same belief, someone is going to get screwed and you're going to have bigger problems. Were the other owners thinking of what was best for the entire league and it's perception when they decided to change the rules based on things the Patriots have had success with or to heavily punish Kraft's team for things they look the other way with when others are involved?
In the big picture, what is this spirit of conciliation gaining Kraft down the road? Something we learned about the deflategate penalties was that the other owners thought the league didn't punish the Patriots enough for spygate. This is BS, revisionist thinking because, at the time, everyone thought the penalties were significant. Goodell even said that he took away the 1st round pick because he thought it would have a more negative effect on the franchise.
The problem was, the Patriots didn't fall back to the pack like the league and owners thought they would. They continued to win, maybe not Super Bowls, but they were the best team in the AFC East and among the best in the league post-spygate. It wasn't that the penalty wasn't heavy enough, it was that the Patriots were good enough to deal with it and continue their success. When the deflated football farce came up, the owners decided this was their chance to really set the Patriots back and Goodell impose an even harsher punishment. Once again, though, the Patriots continued to win. Since the deflategate story started, New England has won 2 Super Bowls and been to an AFCCG. This season, they are on track to be one of the top 2 seeds in the playoffs.
Kraft has publicly stated that he believes envy and jealousy were behind the most recent penalties levied against his franchise. They probably played a big role in the penalties from a decade ago. The reason for that envy and jealousy still exists, so what's to stop the league from "messing up big time" again and banning Belichick for a year because an opponent's headsets failed at Gillette during a playoff game? Doing what's "best for the league" is a noble approach, but when the league has decided that holding your team to a different, unfair standard is in it's bests interests, how can you support that?
