Yeah, I also heard that as well. Seems that Buboy is giving good advises to Manny during the Broner fight. Prior to that we have seen Manny being hit in the last 10 seconds either in the end of 4th or 5th round. Buboy immediately, jump on Manny and tell him to be very careful specially in the last 10 seconds or so to prevent another "JMM".
Not only those two but you have a lot of good welterweights at Al Haymon's stable, Let's see:
1. Danny Garcia (that left hook)
2. Amir Khan (who will be fighting Crawford)
3. Errol Spence (who will be fighting Mikey Garcia)
4. Thurman
5. Porter
All of those are elite WW so Manny can be match with those fighters anytime of the day. And anyone of them may give Manny a good and exciting fight, it will be a test if Manny Pacquiao has that killer instinct if he goes against those top dogs in welterweight division.
