low blow

I was watching the tape of the Mayweather Judah fight earlier and I made a pretty good observation. Between rounds Judahs father was going beserk telling him to go down stairs and upstairs, boom, boom, bam, using sound affects and all. But in the later rounds after telling him all that he would wisper something in his ear making sure that what ever he said didn't come out on camara. Why would he do that? Why was he so worried about some one yhearing what he was saying. Well my friends I belive it was because papa Judah was the one that told Zab to go low. What do yall think?

I think he was talking about Zab's hands. Just like when Roger did it with Mayweather but I heard Mayweather say 'right hand' after the 7th round.
