As rodent rampage pointed out, I would call it unsportsmanlike conduct. Regardless, there is some conduct that I think is cheating regardless of whether there is an explicit rule against it. I would put conduct which the rules commttee labeled as "contrary to the spirit of the rules" which "cannot be tolerated" in that category. If I signed up for a recreational softball league, and the other team bribed an ump before a game, I would consider that cheating even if nobody had bothered to write down an explicit prohibitiion against it. When players take a provision of the rules designed to protect players (injury timeouts) and through dishonesty induce the officials into invoking that rule in a situation where, by the letter of the rule, it should not be invoked (it says play may be stopped for an injured player, not for a player pretending to be injured), I put that in the same category.
If the Gophers did this kind of stuff, and it was systemic like it seems to be with LSU, I would call the ticket office, ask for a refund, and certainly not renew my tickets. With the well-documented struggles of our program, I have spent plenty of money watching bad teams (and I would do it again), but I would have no stomach for watching dishonest ones.
There are two things you can always control in sports, your effort level and your integrity. It hurts to see young players like LSU's so willing to throw away their integrity the way they were in front of such a large audience. Their conduct was disgusting, and detrimental to the notion of fair play. I hope to heck that there is not a coach trying to convince these young men to do this.
