After GGG stops Jacobs in December to go 37-0-0-0, who will he fight next in 2017? Maybe BJS in April then the big one with El Pollo Rojo in September? He'll beat them both easy anyway to go to 39-0-0-0. Marciano and Floyd's record won't be far off from there.
I hope BJS after Jacobs. But 49-0-0-0 record will not happen. I think GGG have 2-3 Years to fight and may take about nine fights from today.
Nice bait job by the OP. To go from who nex to 49-0....... Not happening. If GGG can't get the ol Yeller PPV, he move N to 168, dominate it for 2 yrs than move N again to 175 for bucks vs Kovalev/Ward winner. Once he gets that $8-$10 mil payday, it's back to the quiet countryside of Kazakhstan.
49-0-0-0 is possible. He fights 3 times a year. Next fight this December to go 37-0, then in April he'll turn 35 years old, which is also the time he'll have his 1st fight in 2017. Age 35: 3 fights (April, Sept, Dec) Age 36: 3 fights (April, Sept, Dec) Age 37: 3 fights (April, Sept, Dec) Age 38: 3 fights (April, Sept, Dec) 37 + 12 = 49-0-0-0 So it's very possible, or if he retires at 37 then it'll be 46-0 which is close enough to the record.
Where does the money come from to keep him fighting at MW or SMW in 2020? Nowhere, that's where. I like your thinking, but he's got to get Yeller, or somehow lure Froch out of retirement to earn the kindof money to keep him in the ring. If not, he's gonna have to go to LHW to get back onto the PPV screen after Canelo and BJS are handled, and that means he'll be tasked with the 200lb Beterbievs, Kovalevs and Wards. Not going to stay undefeated vs those guys back to back to back.
