No one who is that deep in delusion enters into an agreement like the one he's now in with you without a plan B. No one in that state agrees to anything that they don't already know how they're going to get around or otherwise gain control over. It may sound harsh, but I'd bet the farm he's still drinking.
I don't know either of you, and am only going by your descriptions. My only advise is to get him the help that you think you can, should, and that he needs -- rather than that which he so readily agrees to (the football stipulation speaks volumes to me in terms of personal recognition). The best thing you can do is to never ever underestimate the sheer cunning of an active alcoholic.
