Bo is a very interesting case. He was a .250/.309/.474 hitter, and that wasn't really adversely affected by his injury. His per-162 numbers were 47 walks and 196 strikeouts, and that's before striking out 200 times in a season was considered "okay". He's got a ton of helium as the greatest athlete ever because he hit amazing bombs and flashed tools beyond anything anyone had every seen in speed and power and arm. The problem was that his eye simply wasn't that great at the plate. His dWAR never graded well, which could be an issue with the statistic or it could be showing us that perhaps our visions of his stellar defense were skewed somewhat. He never had better than a 3.5 bWAR in any season, and while he only eclipsed 500 PA once in his career, a guy like Chipper Jones had three seasons in 2005, 2006, and 2008 where he eclipsed 3.6 WAR every season, despite only having 500 PA in one of those seasons (all of which were in his 30s). Based on all of that, I don't know that Bo would have given a team more than a mediocre average with power and speed, even in his best years (remember that he was able to still play his age 27 season before injury, so it's not as if he never had a chance to hit prime seasons). I would have imagined a .250ish/.320ish/.500ish guy. Valuable because of his arm in the outfield and his speed as well, but I don't know that he would have been the superstar in the modern era that he was before.
