In fact, that kind of rational approach
IS the problem.
It's exactly that kind of breaking down the large goal into smaller sections and judging each one that fails in sports. It's the corporate approach and it's really designed to make excuses for failures, so people can say to their boss, "Out of the six areas we use to judge, he was successful at four, so let's keep him doing what he's doing. We're on the right track."
But this isn't business (as others have pointed out) this is sports. The only thing that matters is winning games. A team can look like it's building and on the right track and doing the right things and improving forever and still never get over the hump and win a championship (like New England, 0-4 in Championship games).
There is no way to measure "progress" on a sports team, no way to know for sure when to blow everything up and start rebuilding and when to just tinker a little more. There's no formula.
That's why sports are so interesting and so frustrating
