Oscar De La Hoya Post-weigh in Weight vs Mayweather?

I've heard claims that ODLH rehydrated 20lbs heavier on fight night, though a more realistic take was around 170lbs or so. Do you guys personally think this is true or just made up to hype up this already impressive victory?

If so how do you think he would have faired against Manny Pacquiao if he had also rehydrated 10-20lbs. From what I heard also online was that ODLH had to take IV drip to barely make 147lbs the next day, and what are your thoughts on those overall claims as well?

FYI I have no idea if any of these claims are true or not, just curious.
