In 1961, after 70-years, professional baseball created its first expansion teams – the Angels and Twins. Naysayers harshly criticized the growth of the league, fearing that new teams would dilute the talent pool and ultimately lower the quality of game play.
Since 1961, professional baseball has grown from 18-teams to 30. Over the same period, professional football and basketball leagues also expanded dramatically.
Although sports purists would no doubt quibble about the impact expansion has had on professional sports, most fans agree that the overall talent level has remained relatively constant, despite the significant increase in the number of professional athletes.
