From the linked article.....
Jones had been extremely critical over many of Goodells decisions, and was vocal over this mishandling of the players protests during the national anthem.
Jones decided to put his money where his mouth is, and hired an attorney in an attempt to stop negotiations for Goodells lucrative contract renewal.
RENEWAL contract - NOT current contract.
Oh, and Jones isn't the one who needs to grow up. The lefty players, Goodell and the NFL are.
Mishandling of the players’ protest that HE PARTICIPATED IN. He didn’t start criticizing Goodell until Eliot got suspended, this is 100% him having a hissyfit because his guy is getting punished. Jones is a cry baby.
