anything that sheds a negative image on the league is conduct detrimental to it, so it doesn't even have to be a conviction to taint the league's image, just the numerous charges that are attributed to Henry and PacMan, you can't be involved in that many charges if you are being a good boy, people are not stupid, and like we have seen, there is an outcry
again, their association w/ law-breaking is casting a negative image, but it's not just them, they are just the biggest and repeated culprits, it all comes down to the number of player arrests doubling from the past couple of years, and Goodell cracking down before it gets into a full-blown problem that the Government would feel that they have to step in, so it's only natural that he go after the biggest culprits w/ the stiffest penalties in hand
but if you are within your rights, how can you be wrong? the better word to describe Goodell's actions are as harsh, but that's what happens when things start to spiral out of control and people want solutions
