Ethics of Fantasy Sports

I have spent an embarrassing number of hours thinking about fantasy sports. Hundreds, probably. Maybe more. And one of the things I keep coming back to is the question of what actually counts as cheating.

People throw the word around loosely. Someone makes a trade you don't like? Cheating. Someone exploits a quirk in the scoring system? Cheating. Someone drafts in a way that annoys you? Believe it or not, also cheating.

I think most of this is wrong. After years of playing, arguing, and occasionally getting yelled at in league group chats, I've landed on a pretty simple definition: any action where all managers involved are not making genuine efforts to improve their own team's position is cheating. That's it. If both sides are trying to win, the move is fair game. If someone is tanking, colluding, or dumping players to help a friend, that's a different story.

Everything else is just strategy. And strategy, even when it's annoying, is the whole point.

Let me walk through a few examples that people love to complain about.

Hoarding Scarcity

This one worked better in the good old days when the only elite shortstops were A-Rod, Jeter, and Nomar, and Chipper Jones went in the 1st or 2nd round because no other third baseman could go 30-100. The game was simple: grab the top guys at thin positions early, and suddenly every other team in your league needs to come to you if they want a premium player. You'd be amazed what people will overpay for a scarce asset. (This is also, incidentally, how half of Wall Street works.)

The strategy has gotten weaker over time as roster formats have shifted, but the principle still holds. Identifying where supply is scarce and positioning yourself accordingly is smart drafting. Nobody is making their team worse by trading for a star they need. Both sides are trying to improve. Call it whatever you want. I call it economics.

Unconscionable Trades

You've seen it. One manager trades with another and the deal looks wildly lopsided. The league chat explodes. Accusations fly.

But the only questions that matter are: did both sides believe they were improving their team? Were both managers acting in their own self-interest? If the answer is yes, then the trade is legitimate, full stop. Every manager paid their entry fee. That buys them the right to manage their roster as they see fit, even if the rest of the league thinks they're an idiot.

Now, I get the counterargument. Sometimes trades really are suspicious, and collusion does happen. But the bar for overturning a trade should be evidence of bad faith. Disagreeing with someone's evaluation doesn't clear that bar. Smart people disagree on player value all the time. That's what makes markets (and fantasy leagues) work.

Pitcher Streaming

This one's a classic, and it drives people absolutely crazy.

In H2H category leagues without transaction limits or IP caps, pitcher streaming is straightforward. You cycle through starting pitchers all week, picking up whoever has a favorable matchup and dropping them after they pitch. If you rack up significantly more starts than your opponent, you can pretty much lock down the counting categories (W, K, IP) while gambling on a coin flip in the ratio categories (ERA, WHIP). Winning 3 out of 5 pitching categories most weeks will carry you to the playoffs in almost any league.

Is this against the rules? No. Does it feel cheap to play against? Absolutely. But if the rules allow it, the complaint belongs with whoever wrote the rules. If you don't want streaming, add transaction limits or innings floors. The person who read the rulebook more carefully than you did is just playing the game.

Look, I know this is a lot of words about fantasy baseball. But I keep thinking about how every competitive system works the same way. People find every edge the rules allow. Always have, always will. The only thing that keeps a system fair is good design. I suspect this will matter well beyond sports as more and more of our lives move online and get governed by rules that software enforces automatically. Whoever writes those rules better get them right, because the players will optimize ruthlessly. Count on it.
