I went back and rewatched that "brawl" starting from where I assumed Butler was at fault. I definitely stand corrected; it looked like the Baylor player was intentionally putting a LOT of pressure on Butler's knee/calf.
That, in combination with the ridiculous late hit into the water table on DM makes me all but certain that Baylor was deliberately trying to injure our best players. There were some other not-really-incidental shoves on DM leading up to that, too.
Just embarrassing how skewed the spotlight turned, and yes I'll agree with everyone saying the refs lost control of the situation far before the skirmish happened.
