Pacquiao is more than likely being played by his own legal crew and can't see it. What his people advise him is that they know how the game is played and to trust them but the truth is they don't have any real experience.

What is really going on a maneuvering by Pacquiao's people to get some of that future prize money by cutting out Arum and Roach.

The tell here is the fact that Arum and even Roach haven't been able to get a hold of Pacquiao. They are intentionally isolating him so they can influence Pacquiao's decision making.
We might see some rational when Pacquiao gets back from the Philippines.

Pacquiao is a trusting person and there are too many unscrupulous people willing to take advantage of that.
