Best case scenario:
Sox win every game for the rest of the season, win world series
--You laud Theo as a genius, the FO and ownership have done it again and deserve ultimate praise. (because it can't be luck)
--17 SUCCESSFUL GAMES FROM NOW
Worst case scenario:
Sox don't make the playoffs. They win zero games out of the remaining 6 and you say that Theo has overseen the most epic collapse in history. He deserves to get fired, but you acknowledge probably will not until the following season.
--6 UNSUCCESSFUL GAMES FROM NOW
Theo will have been with the team for 1458 games but you acknowledge that his reputation and success will be evaluated, in your mind, by somehwhere between 17 and 6 games. That's a small sample size. In fact, that's a sample between 1.1659% and .4115% of all available data.
I think his reputation/skills/success is independent of what happens the next few weeks. I think the quality of a GM is the thoroughness with which they assess their talent, work to make things better, try to get younger, use the resources at their disposal, etc., and their overall track record of success. What happens over the next week really should be compared in context to what has happened over the past 9 seasons, IMO.
