I'd be surprised if there was a rehydration clause, both will come in at LHW(168.1-175.0) if not at cruiser (175.1+).
Anyone who claims Jacobs is being short-changed with that offer is simply clueless. A little perspective here: Chavez Jr purse vs Canelo was 3 Mill. Khan's purse vs Canelo was 2 mill. Canelos purse vs FLoyd was 5 mill. Cotto's purse vs FLoyd was 8 Mill. .....just to name a few. All these guys were considered bigger names and had a bigger following than Jacobs. Jacob's claim to fame is doing pretty good vs GGG. It's a damn good offer and one that he will more than likely never see again.
Those are all just the guarantees. Once the full gate, TV & ppv money came the fighters you mentioned made a lot more money. I don't know the exact number for Chavez Jr, but I believe he got about 20% Khan ended up with more like 10 million Canelo got at least 4 times that against Floyd in the end. Cotto got 35% against Floyd overall. Your point actually still stands (although it's somewhat overstated), but I'm a stickler for accuracy hence the corrections above.
Haha lol. Now that gives me a GREAT idea. What about Anthony Joshua vs Canelo Alvarez? The two biggest stars collide, that'll make tons of money!!!
Im sure Canelo was the A side. Thats just the price Canelo had to pay to get Cotto to agree to fight him.
