certainly possible. He'll be 47 in jan, his legs have been pretty shaky last two fights, anything can happen. Age will get him eventually if he's not careful.
With that said, I personally THINK pascal is a harder, more explosive hitter than dawson. I reckon hopkins will SEE the punches coming from dawson most of the time. Now getting out of the way is another question.
But sure, it's certainly possible.
Props to bhop taking this fight. Showing floyd & pacquiao what "risk taking" is all about.
