Because He proved he could take a beating against those guys due to an abnormally strong chin+roids+his style of fighting. Unlike foster who looked physically frail against comparitively small HWs. I don't understand why you still can't see the difference. The problem isn't fosters talent. I would give a hypothetical roided up 215lb foster with a smart game plan a really good chance. But not frail-KO crazy foster
At heavy you have to favor James, Bob never looked comfortable fighting guys that large. The Toney that beat Evander stops Bob.
To take the bodyshots. Also a more defensive minded strategy than he actually used, then yeah why not
Fosters jab wins the fight, Toney can't get inside and use his know how, plus Bobs punches carry snap.
