Will Bob Arum use Pacquaio as a stepping stone for upcoming Top Rank fighters?

Not anytime soon.

Way more $$ in squeezing Pacquiao as a winner
His political career would have to fail.
He'd have to slow down and loose a lot of power (late 30's?).

I want to bring up your point made about there being way too much money to squeeze out. There's definitely a lot of truth to that. Makes me think that Top Rank are in actually quite a bad spot, as they don't have anyone ready enough to take his throne. There's also a lack of good fights out there to entertain the fans with. And if Pac fights Mayweather, he's gonna want to up and leave after.

if pacman chooses to fight lets say 7 fights, i think he ends up with a roy jones like record. roy jones is a bum

Top Rank used Whitaker and Chavez Snr to build up Oscar De La Hoya.

Thinking about it now, I could see Arum making a Jose Benivadez vs Pacquaio fight down the line. 2 - 3 years from now. The kid has skills.
