They purposefully construct a team each year to be mediocre. We can argue about the reasons, but that doesn't change the outcome. I don't know exactly how much blame to assign to whom, but I'd be willing to bet that whether Jed stays or goes, the team will be mediocre moving forward unless they hit on some draft picks and/or international players. To have an argument or whatever, I consider 88 wins mediocre.
Bad = > 82
Mediocre = 83-90
Contender = above 90
That doesn't preclude them from hitting 90th percentiles and making the playoffs or even winning a WS due to the nature of the format, but it's not what they should be doing given their resources.
