This seems like a subjective thing, I know, but Ken Griffey Jr. was the ballplayer for my generation. The #1 overall pick in 1987, Griffey made his MLB debut on Opening Day in 1989, when he was still a teenager. He was a huge deal right from the start, popular enough that in just his second season, he was voted by fans to be a starter for the All-Star Game, making him the second-youngest position player ever to be so honored. (Only Al Kaline was voted in at a younger age, and by just one month.) By the end of his age-30 season, he'd hit 40+ home runs in seven different seasons. Before Griffey, no one so young had done that more than five times. He made breathtaking plays in center field, the kind every kid pretended to make when he was at Little League practice or alone in his backyard, and won ten consecutive Gold Gloves during the 90s. He finished in the top five of the AL MVP vote five times, winning the award in 1997, and having an excellent case for it in 1993, 1994, and 1996 as well. He was chosen for the All-Century team, despite not yet having turned 30. He was elected to the Baseball Hall of Fame in 2016, having received a record 99.32% of the vote. Only a fool would leave Griffey off their ballot.
