In chess, after the round is over you'll see a couple of great players sitting in the skittles room analyzing their game. There will be several dozen lesser players (such as Dr. D) standing around "rubbernecking" the action. The "kibitzer" is the Class C player who is making suggestions. 90% of the time the "kibitzer" has no idea of how his kibitzing is being received...
10% of the time the kibitzer is a strong player, and when this is the case, now you've got a fascinating three-way dynamic between the two masters, seated, and the "editor" who is serving as a kind of reality check on the argument.

On paper, it is perfectly obvious -- to saberdweebs like Thirteen and Dr. D, and also to any garden-variety birdbrained beat writer* -- that teams are giving away a HUGE advantage by reserving "Closers" for "save situations." In one of his books, James calculated an 800% advantage for a team willing to use its "closer" in tie games OR WHEN BEHIND BY ONE RUN. He finished, acidly, "As baseball percentages go, 800% is a big advantage."
