It is an odd time to be a fan of the Chicago Bulls. That has been true for roughly a decade, to be sure, when Tom Thibodeau’s empire of blue-collar excellence expired. Those Bulls never won a championship, or even came especially close, but they were somebody-firmly, ferociously identifiable, a passionate bunch who inspired feelings of grandeur. A bottoming out followed that era, and now we’re into year five of something in between those two realms.
