As your resident alcoholic, I can take this one. Sometimes you're not looking for answers. Sometimes you're just trying to not look for the answers. Sometimes your mind is racing with thoughts, or ideas, or regrets of things you've said or done (often times while sober) and all you want to do is to not think about it anymore.
Most coaches have pretty active minds (like mine). You have to in order to deal with game planning, setting up practices, recruiting, dealing with boosters, marketing, interviews.... Sometimes it's great to have a few drinks and turn that mind off. Sometimes you need a few more.
How about stuff you regret? Why is Sarkisian getting a divorce? I've heard rumors from people I knew that was involved in Washington athletics. Now that his marriage is falling apart, I'm guessing the regret is sinking in hard. Is Sarkisian looking for an answer with alcohol? In my experience, no. He's using a bottle to stop the constant thinking about what he's done not trying to find the answer.
I've really never understood people that say, you'll never find the answer in a bottle. Sometimes all you want is to stop looking for answer and turn your brain off.
