Deion Sanders blew him away.
First of all at their primary position in their primary sport, Bo was never the best at his position any of the 4 years he played and never got a thousand yards in a season. Don’t believe me? In 87 the best running backs were Eric Dickerson and Herschel Walker were tops when looking at the combo of total yards, TDs, ypa etc... In 88 it was the same two plus Ickey Woods, James Brooks, and Roger Craig. In 89 it was Eric Dickerson, Barry Sanders, Thurman Thomas and Christian Okoye. And in 90 it was Barry Sanders, Thurman Thomas, Barry Word, and Marion Butts. That’s why his career highlight was his only in 1990 Pro Bowl nod as a backup. Conversely, Deion was THE best corner in the NFL most of his career and had 9 first team AllPro Selections as a corner PLUS 2 separate first team AllPro selections as punt and kick returner.
Second of all, just talking football....Deion was a multi role player. He’s literally one of only two players in NFL history to score six different ways (rush td, receiving td, punt return, kickoff return, interception and fumble). And he was not in those other roles as a token of his stardom, he produced. He is still THE ONLY NFL player in the modern era to not only play on both sides of the ball...he STARTED on both sides of the ball while simultaneously being the punt and kick returner. One year he was the second leading receiver for the cowboys behind only Michael Irvin and ahead of Emmitt Smith and Darryl Johnston.
Then in other sports Deion eclipses Bo in baseball quite a bit. Deion Sanders finished with a career .263 hitting percentage and .319 on base percentage over a 13 year career to Bo’s .250 hitting percentage and .309 on base percentage over an 8 year career. Deion’s best year was 92 where he batted .304 for a .346 obp compared to Bo’s best in 90 where he batted .273 for a .342 obp. The one thing that Bo gave that Deion didn’t was homers (not that he was a wrecking crew but in his best year he did hit 141 in his career to Sanders 49) but that is offset by Deion’s many steals (186 to 81) and the fact that Deion was one of the better defensive centerfielders in the game while Bo was a defensive liability and frequently played DH along with his official position of LF.
Just for further clarification, Deion is the only person to hit a homerun in the MLB and a td in the NFL the same week. He’s also the only person to play in both World Series and Super Bowls.
