Professional sports has a "no returns" policy

Fantasy sports are like real world sports in one way. All it takes to ruin a season is one dumb trade. This is why anyone who plays fantasy sports will tell you that subtly encouraging a distracted buddy into making a really dumb trade is advantageous AND fun.
