Mayweather has to be more cautious than Manny because he is undefeated, and for some reason everybody thinks he is a natural welterweight, if he beat Magarito like Mosley did, people could simply say Margarito was overrated. If Mayweather beat Cotto the same thing, Mayweather was expected to win. Even in outboxing Oscar, even Jim Lampley stated around round 9, "I knew all along Floyd was going to win, but I am surprised how well Oscar has done to stay in the fight". WTF Mayweather was only a 2 to 1 favorite, Oscar looked great against Mayorga, he was the best fighter Mayweather had ever faced, and it was at 154. Mayweather gets no credit because he is expected to win every fight.
