Not disrespect intended, but your statement is a little silly. Mayweather does not train like he is preparing for a 15 round fight, that would be pointless and potentially costly to him.

The training and tactics used for 15 round fights are a lot different than for a 12 round fight. If Mayweather was capable of performing another three rounds at the level he was showing for the 12 rounds against Judah, then he needs to question his inept trainer.
