Does anyone know what this font is?

It's still possible or even likely that "Bengals" script is a unique, bespoke lettering design. It's not the most attractive script. I tried skimming through a couple Cincinnati Bengals PDF files, such as their annual media guides, looking for a flat, straight-on example of that script lettering. Such an example could be used to run through various online font ID filters. I didn't see anything that matched.
