I guess I don't really understand the "it isn't unique enough" criticism on the Shield. Set aside for a minute the fact that we have, for all intents and purposes, an empty visual toolbox. You're not looking for something that stops traffic - you're trying to land on something that is both easily and quickly recognizable and would work in a variety of settings (helmets, polo shirts, stationary, business cards, etc.) - with the latter point being really important for us because we don't really have anything else (before the rebrand, this where the "column I" came in).
This is an old video that's probably been shared before, but
check out Aaron Draplin building a logo expressly out of existing, familiar things. This is a good approach for anyone, but especially for us - we're an old Midwestern institution, not an NBA expansion team. I'm convinced that one of the reasons the 70s script feels so right for everyone is that Illinois is a brand/team that FEELS like it should have a classic iconography that you've seen before, even though we all know that we do not.
