Pacquiao is an elite fighter and he is supposed to fight tough dangerous opponents. He is trying to fight Mayweather now. Pacquiao has been fighting dangerous fighters and that helps his popularity and makes him money. When he fights safe easy fighters like Algieri he loses popularity and credibility and makes less money. pacquaio is'nt elite enough to fight different against an opponent that has given him problems since fight #1. he's so elite that he got put to sleep.
Is it really rocket science? They select the best fight available for Pacquiao that can be made! Until Pacquiao kills Marquez, Marquez will always fit this bill...unless he moves to Al Haymon! Pacquiao does not operate on the principle of avoidance.

Well, when the second fight happened, Pacquiao wasn't a huge star yet. Also, after the first bout, which ended in a draw, there was always a big demand for a rematch especially in the Mexican crowd. When the third bout happened (Pacquiao was a big star by this time), I think they thought they could bring Marquez up to welterweight like Mayweather and finally beat him. That ended up backfiring on them, and the result was another disputed decision. The fourth fight then made sense financially as Top Rank had a limited stable for Manny.
