Why did manny stay with bob arum?

[imp]

My guess, (and it's only guess because I have absolutely no proof to back this up) is that Bob knows about the PED use and will out Manny if he ever leaves.

I just think other people are making too much money off him whilst he is with top rank and it suits them for him to stay there..

Manny isnt earning crumbs at top rank and he will retire with millions in the bank but surely for the last stage of your career why not take a risk and get as much money as you can like oscar and floyd have...

He is now with top rank until the end if 2016..do even the pac fans agree with this..?
