Not a direct one, though check out James' preamble in his Win Shares book. It's one of the smartest things written about baseball numbers that's ever been published. Doesn't make WS the be-all, end-all system, but what he gets right goes a long way toward ameliorating what he gets wrong.
What Win Shares has got in spades is rigor. James applied it to the whole of baseball history and the individual performances on the team roll up to the total team value. Try that with a holistic linear weights system and you'd be looking at a disasterbacle of the highest order.
