After winning a Heisman Trophy and making a Pro Bowl, Doug Flutie has set his sights on an achievement of a different variety. The retired quarterback will compete on MLB Network's <italics>The Next Knuckler</italics>, a reality show in which former Boston Red Sox pitcher Tim Wakefield teaches a group of former college and NFL quarterbacks to throw his famous knuckleball. The competitor who shows the most promise will get an invitation to try out for the Arizona Diamondbacks at spring training. Flutie's attempt to add knuckleballer to his resume got us to thinking of other football-baseball dual-sport athletes since 1970.
