Or the Browns could just honor his wishes and allow him to leave. Of course if they want to add insult to injury they could force JS into a marriage he hates being in. I don't see how anything productive could come from that.
Just out of the kindness of their hearts!!!! If they do they would owe him $$$ for releasing him of his contract. Maybe if he forfeited that $$$ but I doubt he would do that. If another team like Pittsburg wanted to hire him do you allow him to go there for nothing? That is not good business.
At some point people need to consider the long term ramifications of their actions. Let me explain what's not good business. Showing every coach on every level in the NFL that you are a team that will hire a new HC and then force a DC that doesn't want to work under the new HC to stay. They've already shown that they wanted to force a new HC to only have control of the offense and keep the current DC. That disaster didn't end well.
As if the Browns didn't have enough trouble in the hiring process at HC this time, actions like that will make it even harder the next time.
