With due respect to Bosworth, BO Jackson pretty much had a great influence in ending Bosworth's pro career. Bosworth was never quite the same after Jackson powered over him over in the Raiders vs Seahawks game in '87. After that hit by Jackson Bosworth's shoulder was never quite the same.
Barry Switzer, the old school hard nose coach of Oklahoma, kicked Bosworth off the team for steroid abuse. Bosworth was picked up by Seattle in a supplemental drift as #1 pick.
Bo Jackson played MLB before signing with the Raiders, and played well. Once broke a bat in half his knee after striking out. (think it was for striking out) .
Jackson was natural powerful and gifted athlete who probably could excel in any sport.. Bosworth was a great college football player, but that does not always transfer over to the pro's. Long list of college stars who never quite made it in pro football.
