Did you know track star Carl Lewis was drafted in the NFL as well as the NBA?
The Chicago Bulls drafted Lewis in the 1984 NBA Draft as the 208th overall pick, although he had played neither high school nor college basketball. Lewis never played in the NBA. Ron Weiss, the head west coast scout of the Bulls, and Ken Passon, the assistant West Coast scout, recommended Lewis because he was the best athlete available.
Though he did not play football in college, Lewis was drafted as a wide receiver in the 12th round of the 1984 NFL Draft by the Dallas Cowboys. He never played in the NFL.
So it is not strange to see guys get drafted by other sports. Lately, Johnny Manziel has been getting drafted by other leagues, but it is not unusual.
