The reason why both gambling and PED's are illegal is because both undermine the integrity of the game. Fans need to know that the team that won, won fairly, and played according to the rules. If players are gambling on the game or using PED's, that integrity is shaken. In both cases, fans are no longer certain that the the team who won, won fair and square and played according to the rules of the game. Because of that, they both should have similar, extreme penalties.
