As Manny and FLoyd sis both figure on such show more than any other fighters, I am not sure that it would be that interesting anyway. The cool thing is to discover or rediscover a new time how they train, how they manage camps but personally, I'Ve seen Floyd and Manny so many times on these shows that I am not interested to see the same damn places once more.
Plus, as it has been stated, this show sold itself overnight. 5 years of waiting just did that.
