The 1975 Kellogg's set was a mere 57 cards deep. For the most part it was comprised of veteran players. George Brett wouldn't be found in cereal boxes until after he had won his first batting title in 1976. So despite finishing 3rd in Rookie of the Year voting in 1974, Brett was not part of the 1975 Kellogg's set. Still, how cool would it be to have a 3D rookie card of a future Hall of Famer? And following the line of thought from my previous post, Brett is the only player to go into the Hall of Fame with a Royals cap on his plaque. He was drafted by the Royals in 1971 and played his entire 21 season MLB career in Kansas City. While the other 4 of my picks can certainly be disputed, there can really be no other player at number one.
