Biggest rehydration between weigh in and fight night?

I think when he fought at 126 he would rehydrate all the way up to 144. Huge rehydration for a smaller guy. no that was when he was fighting as a junior lightweight..he would weigh-in at 140-144 on fight night.. pac rehydrated about 12lbs against marquez in their first fight at featherweight.. http://t0.gstatic.com/images?q=tbn:ANd9GcR4ExfUivJKm5iC7D3FN-DosqeIiNU0j94ccCK4lARWNi_ci_e2PujYJ5yJ

PAC was a huge Rehydrater at the lower weights I think when he fought at 126 he would rehydrate all the way up to 144. Huge rehydration for a smaller guy.

joan guzman for the first funeka fight weigh in was 133.5 then hydrated to 152

PAC was a huge Rehydrater at the lower weights

didn't Cotto go up like 17 lbs when he fought Corley at 140?

in terms of the percentage i think donaire and gatti are both up there, because they are not huge guys. donaire was enormous at 112 lbs in terms of overall weight i'd say it's chavez. the guy puts on 20 + lbs in 24 hours. Donaire wasn't huge, against montiel he put on 8 to 126 when montiel out on 16 I think which is Huge! Use percentages to figure out who's the worst because there's a big difference between Chavez putting on 20 and montiel 16

charlie Z rehydrates 2 tons with each ton distributed to each of his fists. which explains his monsterous 3500 psi

Gerald McClellan needs a mention, the guy rehydrated serious weight.

roy jones was 180lbs vs bernard hopkins(first fight) and said he did it often chad dawson occasionally gains 20lbs from weigh in to fight night I have no idea how bad chad is going to make 168 if that's true. His frame looks ways too big for it.

he was close to 170 for the diego corrales fight How do you know that? It was on Showtime. They don't show fight night weight. Did he say it somewhere in an interview? He certainly didn't look anywhere like a middleweight to me at least.

Danny Romero used to fight @ 112 and come in around 130-135 which would be 16%-20% more than fight weight.

In the last Clottey tale of the tape with his weight I remember seeing, he was only 155. he was close to 170 for the diego corrales fight

Joshua Clottey usually enters his welterweight fights at something like 170 pounds. In the last Clottey tale of the tape with his weight I remember seeing, he was only 155.

I dont know if its true but I heard Lucian Bute gains at least 20 pounds after the weigh in.

I'm sure Hatton was a hench re-hydrator. 160 or there abouts come fight night.
