Some of the most lucrative and expensive player contracts in sports history are baseball contracts. Major League Baseball is not subject to salary caps like professional basketball, allowing baseball players to sign contracts for large amounts of money, often totaling many millions of dollars over a period of years. The very best professional Major League Baseball players may be able to make over 100 million dollars during their career, though this top tier is reserved for only a select few. As of 2008, only around thirty Major League Baseball players have managed to go above the 100 million dollar mark in lifetime earnings. Still, even average or below average players regularly have multi million dollar contracts. Critics have argued that the large sums of money paid to professional athletes has gotten out of hand, and they point to the multi million dollar deals common in professional baseball as an example.
