Here's my hot take for the evening: Dude be trollin'.
Keep in mind this isn't the first unsubstantiated rumor this season about Bo's dismissal. Red Sea Scrolls was dead sure Bo was gone in the wake of Audiogate, and so tweeted. Anonymous people have been unqualifiedly asserting that Bo is done all across the interwebz after each loss. I don't understand why this rumor seems any more legit.
Plus, maybe it's just me, but it's sketchy when these blockbuster leaks occur late at night. BS is ferretted out quicker during the day. If I wanted to start a rumor, I'd do so late so it could fester overnight.
Finally, the part about Bo resigning (as opposed to being fired at the end of the season) does not pass the sniff test. The only reason I can think of for why a HC would resign would be that there is some very dark dirt about to be exposed. I don't think that's the case with Bo. I find it hard to believe that that Bo, or any HC at a major program, would resign out of a sense of honor. Has anyone ever done that?
If a school wants to fire the HC for poor performance, it pays whatever penalty is in the HC's contract. Bo, or any HC for that matter, isn't going to turn down liquidated damages out of a sense of selfless devotion to the school that wants to kick him to the curb. Plus, I thought there was some recording where Bo tells Nebraska that it can stuff itself.
