It proves that if I want to know about who’s going to win a hockey game, I should ask you and not necessarily my rav, unless he has much more hockey knowledge than I think he does.
Really? If I once predict the outcome of a sporting event, that proves to you that I’m an expert?
And if your rav would predict who would win a game without any significant knowledge or research (assuming hypothetically that there was significance to the answer), I would tell you to get a new rav.
