I never had an issue with the stoppage but for those who did here is video proof that the Floyd Mayweather KO-4 over Victor Ortiz was leagl.
Joe Cortez clearly restarts the fight at the 1:03 mark. He makes the signal and says "Let's Go." This would mean the fight is restarted.
What Cortez does after that is irrelevant. If he looked at the time keeper or judges, it didn't matter. Ortiz was to busy wanting to hug it out and that isn't something Mayweather needs to be worried about.
Oritz didn't protect himself and Mayweather dropped him like he should have. This wasn't a sucker punch. This was a legal punch that was a result of Ortiz throwing the most illegal headbutt ever.
