The article has a hodge podge of information about Pac, Mayweather, and Mosely. It has a the following quote from Roach about Pac fighting Mosely:
"Shane came to the gym twice to ask me to let him fight Manny," Roach says. "I told him no both times, and both times for the same two reasons: First, there isn't enough money there, and second, you're too good a fighter."

Everyone talks about Mayweather ducking opponents and cherry picking but in the end I think it is just about business. No one markets a fight better than F. Mayweather with the exception of ODH. One writer commented:
"As for Mayweather, I remember sitting down with him about eight years ago in an arena filled with mostly Latino fans screaming for a Mexican fighter, and he muttered "I wish I was Mexican so I could have these fans." But after signing to fight De La Hoya in 2007, he discovered he could bring millions of fight fans to watch him by using tried-and-true pro wrestling antics. Now he sits as one of the most marketable fighters in a matchup that has taken 10 years to finally nail down."

It was outlined really well in the article by D. Greisman Ask Not What Boxing Can Do For You (posted on boxingscene 02/01/2010).
