Was the "bump" classed as a major violation on its own merits, or was it elevated from minor in conjunction with the unethical conduct charge? Is it set in stone as a major violation, or is there a chance that Tennessee could have it reduced to a minor on appeal? In my opinion, no one likely has enough information to make an well-informed judgment on this particular charge. The letter itself doesn't explain why the "bump" was classed as a major infraction, so the NCAA's motivations for such likely remain only within the Committee on Infractions itself. The university knew about the "bump" violation prior to receiving the letter (although the public did not), so it's likely that they have an account (potentially biased) of the events. However, I haven't seen anything about the "bump" aside from the NCAA letter and resulting internet speculation.
If CBP went to Oak Hill with every intention of improperly contacting a recruit, then the outrage is appropriate. However, just like in the cases of the numerous police run-ins of Tennessee athletes in the past few years, there is a process. The administration apparently has both the time and the desire to see it out. Counterintuitively, many unaffiliated message board posters apparently have neither.
What was the last major incident at UT? Bar Knoxville, right? Plenty of fans were up in arms about it, but as the process moved along, the wait-and-see approach taken by CDD turned out to be the correct one. I'm pretty sure that Myles was the only casualty, and he was already on thin ice. For everyone else involved, it's basically a non-issue at this point.
Obviously this investigation is really unlikely to become a non-issue, at least not for several years. However, the "bump" violation potentially could, at least in the absence of future details to the contrary. It alone shouldn't be changing any opinions on the proper course for UT's administration to take. Yet.
