Of course it's a metaphor. the point he is making is that owners speak of their businesses in terms of revenue/expenses: how much did they take in, how much paid out. Normally they make gigantic profits, which they then keep (since players are merely salaried employees); they don't hand out end-of-the-year bonuses to players when the profits are large. Yet this year, when there are going to be losses, they want those losses shared by players (which of course they will be, in all scenarios). (A point that I believe he makes elsewhere, but not in his recent article, is that the accounting is to some extent bogus: the actual value of franchises is rising, and owners are increasing that value by investing in new stadiums etc. So if a franchise, say, doubles in value, and the owner then sells it, the owner gets a fortune, the players get nothing. e.g., the Clippers players didn't get a nickel when Sterling sold the team for $2.1 billion [i forget what he paid for it years ago, but it was paltry]).
