Underdog versus favored puncher fights

I don't recall Holmes being considered a big puncher. He had good power but was never considered a banger. He could hurt you and take you out nonetheless. Holmes was more favored due to being the best heavyweight at the time fighting a guy who had was the best light heavyweight(and who's career was established primarily there)

Anyone know if Cooney was favored heavily over Spinks? He possessed even more power than Holmes even if his boxing skills were not up with his.
