Where this analogy falls short is I don't think anybody is saying speeding 10 over on the interstate should be legal and shouldn't result in a ticket. I'll go ten over on the interstate and if I get a ticket I just pay it. It's a risk/reward thing However, I will not speed at all in a school zone. It's still pretty much a risk/reward but the upside (a few seconds of time savings) is not worth the downside (a huge ticket with lost points and the possibility of having to live with injuring or killing a child).
The way I see it, it's not an issue of what Mo did being harmless or common behavior. It's just the simple fact that what he did is currently illegal and against University and probably team rules. Maybe it shouldn't be but it is. IMO it's not something that should result in him getting booted but people that get too many speeding tickets and/or have other moving violations (ie felony charges in another state) just might find themselves losing their drivers license.
