While historically accurate, another reason that the weight of the C makes sense in the secondary logo's context is that The C had to have a substantial weight to offset the weight of the bear... I couldn't imagine the C getting too much thinner than how it currently is without looking a little less sturdy. At the very least, there is a standardized C, because in doing the research, there were instances amongst different sports where the block C was much heavier than others, and altogether inconsistent in its structuring.
The Sather font carries some of the key characteristics from this iteration of the block c, but is weighted so that works in numerous contexts.
If you notice on campus, there is currently a lot of equity in the Block C, as you can see it on Tightwad Hill and also the bleachers in Memorial Stadium... I get producing brand assets for merchandising purposes, but, and no disrespect, what was produced really got away from what the brand is all about when you consider it holistically.
