In the 80s and 90s, few sports stars loomed as large as Bo\xa0Jackson. A Kansas City Royal\xa0and\xa0an Oakland Raider, he was the rare athlete to play two professional sports. His strength and power seemed supernatural. He soared into end zones, ran the 40-yard dash in 4.13 seconds, hit meteoric home runs, and broke baseball bats over his head for fun. And those were just his documented exploits. Because Bo played in an era before smartphones, stories circulated \u2014 that could never be entirely proven or disproven \u2014 that he was capable of even more impressive feats. The guy was the stuff of legends.\n\nFor this reason, Jeff Pearlman has entitled his new biography of Bo:\xa0The Last Folk Hero.
