I'm sorry, but the "after football season" literally made me laugh out loud. Mostly because I was THAT sick at one time too.
His quitting should have absolutely nothing to do with you, your threats which so far have been empty, or anything else besides what he wants for himself. It doesn't sound like he wants to stop drinking. I didn't stop when I almost killed me. I didn't stop when it wrecked my marriage. I stopped when I was done, and I know that sounds selfish or whatever, but it's the truth. I didn't CARE if it killed me or destroyed my life, I was incapable of thinking that rationally during active addiction.
Please focus on YOU.
So now I take it you're not asking him to leave anymore?
As for the 'cravings', there's a difference between physical cravings and mental obsession. After abstinence, physical cravings can disappear in a few days. Sobriety has very little to do with recovery.. if he is not working on recovery.. the obsession and potential for relapse will be endless most likely.
