Well this fight is extremely risky for Pacquiao. Don't expect him to have an easy time dealing with Algieri. Algieri is a tall, lanky counter puncher. Who brings no name recognition to the fight. As a result Pacquiao and Algieri are having to promote this PPV fight by continually bringing up Floyd Mayweather Juniors name at the press conferences.
I can see Pacquiao winning this convincingly possibly through winning every round due to activity. I can't see him stopping Algieri. I can also see this being a nightmare fight for Pacquiao. Algieri could potentially pull off a major upset if he fights defensively and tries to box for 12 rounds and not engage Pacquiao.
