OK, how about leave the current paragraph since that is cited and official from the university, and make an ancillary section after the mascot discussion devoted only to the relatively recent contention on the sobriquet?  It needs to be proportional and provide proper weight, but cover all the information available. The university stance went uncontested for 102 years before a source offered a differing explanation, and Dr. Eagles does admit the origin is truly unknown and possibly unrelated to black jargon of the time.  Thoughts?
