19. Tony Gwynn
Tony Gwynn was two-sport star in college at San Diego State University, playing both baseball and basketball. Gwynn played point guard for the Aztecs and set school records for assists in a game (18), season (221) and career (590).
Still, Gwynn ultimately chose to play baseball professionally and made a wise decision. Gwynn had a ridiculous .338 career batting average across 20 MLB seasons and was a first-ballot Hall of Famer.
