Any dual career as a football coach AND rapper is bound to run into conflicts, like when you think about depicting the sale of narcotics from an ice cream van, because that's something that happens from time to time. You think about depicting it, and then you do it, and then you're fired for making a video where someone's selling narcotics out of an ice cream vanbecause you teach at a public high school that frowns on this kind of thing.
Firing him is probably a bit over-the-top, because generally we don't like people losing jobs at any level, particularly when they're well-liked and do a good job. We mean, it makes sense, but just suspend the dude or something instead of hauling off and axing him. That's what suspensions are for: you were dumb, and we now have to do this dumb thing. Firings are for malicious negligence, not moments of poor judgment that don't hurt anyone.
That's the first item of interest from the video. The second?
Putting the real Don in the video might have been the true mistake here, tbh.
