Jackie was known as the athlete of the family. Played on his school’s Baseball and Football teams before the group blew up.
Michael never had a chance to develop athletically the way the elder brothers did. He was 7 years old when Joe put him in the group and 10 when they got signed to Motown. The ENTIRETY of Michael’s youth was single-mindedly focused on music and performing.
If they would’ve had a dance-off Michael would’ve smoked him.
