I cannot stand stuff like this. You want this to be a business? Ok, treat it like a business. If I leave my job for a competitor, guess what I get? Not a celebration of my efforts, I get my personal **** boxed up and walked to my car. To be clear, hate-Tweeting, etc. is awful and shouldn't be done. But this idea fans should support you in your new endeavors is dumb.
Now, more than ever, you have to realize we aren't rooting for the players on a personal level. I have zero personal investment in Jeremiah Cooper making as much money as he can. The only way I know Jeremiah Cooper is what he does on the football field. I rooted for him because he helped the team I root for. I can understand his choice to leave, but you can't expect fans to support you on the way out.
