Do you consider a season successful if you win the division with a losing record?
The record reflects you didn't do well yet somehow lucked into the playoffs. We're winning right now, but part of the reason we're talking playoffs is our division is really bad.
Personally, I judge the braintrust by growth. Have we seen improvement this year? Yes. I'll judge this braintrust as improved when I see 4 more in a row, rational decision making regarding our QB room, and multiple back to back winning seasons.
If we judge by single season effectiveness alone, Nippleshorts was the greatest GM we ever had.
