Currently, people are making a huge deal of the "bump" violation because of the timing of it (obviously terrible) and because of the major violation classification by the NCAA of what is usually considered a minor violation.
There are a few reasons why the NCAA could have decided to class Pearl's "bump" violation as major. Not all of them have to do with the nature of the violation itself.
Should it be a huge deal? Maybe. There are definitely circumstances that would make it a huge deal for me, but I haven't seen any evidence of those circumstances yet, beyond some guessing at the NCAA's intentions. It's still entirely possible that the violation was just unlucky and (probably) stupid rather than flagrant and (definitely) stupid. I don't see how the university would abide CBP flagrantly breaking the rules so soon after the PC, so perhaps there's more (or less) there than meets the eye.
