But things weren't working. They're only just recently getting back on track. At what point does a player taking wins away from his team override this unquantifiable concept of team chemistry?
First, WAR isn't a set in stone "hard" number. It is an approximation. Granted, it is better than "the eye test" but it isn't an end all be all. If so you could automate managerial tasks with Excel spreadsheets.
You would have been hard pressed to sit Mike and not Josh and Nap and many others that were also sucking at the time. Yes, Mike has sucked all year. But in the recent team funk you couldn't point fingers at one player. Benching mike would have attempted to do just that.
