First I want to clear something up, I want no part of dissing Bo Jackson's talent. Absolutely phenomenal athlete. With that said this "There's barely even a worthy discussion to have in the comparison." attitude is at best flawed and at worst delusional. I am exaggerating not in the least that there are literally millions of people that watched both play and would find the above quote simply laughable. Honestly, I don't have a huge issue with anyone that expresses the simple belief that they'd rather have Bo over Hershel. Hell, I honestly wouldn't have a problem with someone saying they'd rather have Barry Sanders than either. (If we're going to play the "fewer carries" argument how many yards does Sanders put up with no Thurman Thomas upper-classman in the way or he just stays for his Sr year?)
A good while back the best I could do with these two is this;
If I've got to have this carry go the distance of the field (nevermind what the scenario would be to make that a running play) I'd probably want to pitch to Bo. (Though Walker was actually faster)
If I have a game I need to win, including grind it out yards and 4th and goal from the 2 situations then I'll take Walker.
