What happened: The Rockies outfielder played running back and defensive back at Scranton High before choosing baseball. An injury shortened his senior season to eight games, when he scored 30 touchdowns.
Why it matters: His football background helps explain the speed and versatility McCarthy brings to Colorado. He earned first-team all-state honors at running back in 2014.
By the numbers: McCarthy rushed for 6,080 yards during his high school career. He recorded 28 100-yard rushing games, including 12 with at least 200 yards.
What to watch: McCarthy's late-season production for Colorado is the next on-field benchmark.
