I am not 100% sure but I thought he had some off field issues or something.
I don’t remember hearing anything specific
I’ll ask my buddy who’s a huge raider fan. He should know why he was released
I do remember hearing/seeing a story that King was intimidated by Gruden and bought him a box of Snickers to give to him when they met (because of the snickers commercials) and because he always heard that Gruden could be grumpy
So he thought it would be a funny way to introduce himself
But he never got to give the box of snickers to Gruden because he never got the opportunity to meet him. Gruden had his ST coach release him with out ever even meeting King
I think that might have been on one of the All or Nothing episodes
