first of all, I also unironically think they should have kept "The Washington Football Team". the goofy iconoclasm and lingering self-awareness of it just cracks me up. "Pigskins" is great too, but maybe too on the nose.
anyway, I think it's hard to speculate about any specific chain of events leading to a Blackhawks logo change. the fact that our logo/name aren't obviously racist sure helps its long-term retention.
honestly, the main issue is that there's no clear, cohesive, public message whether our team imagery is appropriate, in the eyes of the very people depicted by such imagery.
in this thread, we as non-Indian hockey fans have relied on anecdotes, because that's honestly the best we have to justify keeping the logo.
all this may indicate that Indian people are totally OK with our imagery, but I do think it's troubling we can't know that for sure.
that being said, since it's not known for sure, I bet the logo stays as long as there's any Indian imagery in pro sports.
