Of course, there is the danger of a fight like this that could be like Roy Jones. If we recall Jones was KTFO by Tarver, and Jones decided to fight a good, but limited pressure fighter in Glen Johnson. The universal thought was Jones would easily beat a lesser skilled opponent like Glen Johnson. But of course Johnson ended up beating his ass and knocked him the fuck out.
The difference here I think is Pacquiao took an entire year off between fights, whereas Jones fought Johnson about three months after getting KTFO by Tarver. I think Jones didn't allow proper time to heal from a severe concussion. Pacquiao I believe was smart resting a year.
