Professional baseball contracts have long been criticized for their excessive signing bonuses and salary payouts, and critics have long argued that restrictions or caps should be imposed on baseball contracts. 2008 was no different in terms of excessive baseball contracts, as professional teams continued to offer multi million dollar contracts full of special perks to their top players. As of 2008, over thirty Major League Baseball players had earned over 100 million dollars over their career in salary alone, which does not include money made from bonuses. Signing bonuses are often paid to players in order to entice them to sign a baseball contract, and these bonuses are sometimes worth millions of dollars on top of their multi million dollar contracts. Performance bonuses are also regularly included in baseball contracts, allowing baseball players to make even more money on top of their salary if they perform well in their games.
