By demographics, Boston is only like the 10th richest baseball market, and in terms of population it's less than that.
Overall economics dictate that without brilliant work by the ownership and front office, to say nothing of the rabidity of Red Sox fans, this team should be sustaining about half the payroll it is in fact sustaining.
I bring this up because some day, this franchise will be mismanaged, instead of managed at a brilliantly elite level as it's been over the last decade or so. Or some day ownership will lose the ability to finance an absurd payroll. And the difference will be very easy to spot.
I don't think we'll ever be a poor team per se, but if Henry gets tired of losing money, or his heirs do, and insist that the Red Sox pay for themselves, we'll feel the difference. If the front office loses their feel for the pulse of the Nation, we'll feel the difference. We aren't always going to be able to keep up with the Yankees, and should appreciate it all the more when it happens for the times when it won't.
Basically, this is a decade long summertime for the Sox. We always should be a good team, and we're at the zenith of our strength right now. But sustaining being one of the 2 best teams in the league in the league is a stretch we're managing because of great franchise leadership -- not good, great. So love it while it lasts. One day it will not be here.
