Absolutely. But you would have to question, even if the nfl didn't care, would another opener sign off on hiring another player that owns part of another team that you compete against?
This is why it makes no sense. He's not Jackie Moon owning the tropics. He's asking for part partial which no team will sign off on and that's probably going to be a question come combine interview time is he was being serious. Even if he wasn't, in sure he's already rubbed probably 4/5 of the owners the wrong way about it.
