There's at least a half dozen ways this could have been resolved but ONLY if they wanted to resolve it.
Moving it would have required a minimal amount of effort but mostly would have resulted in some backlash from a smll number of vocal professors, admin, etc. that absolutely hate athletics. Our weak leadership would rather screw over the fans than face hearing from that small group.
I hate to make a political/cultural comparison but it's kinda' like irritating conservatives vs liberals or Christians vs Muslims. The fans are like the former groups, i.e. we'll complain a bit but it won't make much of a stink, whereas those attending the event are more like the latter groups and will be a much bigger thorn in the side of the administration if they are forced to make a change due to silly old athletics.
Not only did the administration take the path of least resistance, they also likely support it.
