CMV: There is nothing wrong with an athlete betting on themselves.

There is an obvious conflict of interest should an athete place a bet against themselves.  It is also illegal to engage in illegal gambling (duh!). But so long as an athlete places a legal bet on themselves I don't see any ethical dilemma or conflicts of interest that aren't already present.  That is, for instance, an athlete tempted to cheat because of a bet already typically has ample incentive to cheat.

Now I can see a scenario where it could be argued that public betting could make a culture that pressures others to also make bets against their better judgement.  Perhaps to avoid criticism such as, "the QB clearly isn't confident as they did not bet on themselves in the Superbow."  (How fun that gamesmanship could be.) So let me add another stipulation - the bet must be anonymous.

In summary please CMV: there is nothing wrong with an athlete placing a legal and anonymous bet on themselves.

For a QB to bet on themselves, they generally would have to bet against some spread.  Therefore, the QB would not just be trying to win the game, but beat the spread.

For example, they might try a more risky play on a 3rd down at the end of the game, knowing they need a touchdown to beat the spread, vs just a field goal to win the game.  

That’s a clear conflict of interest.
