the weakest in fighting, i think is unohana, we haven't seen her fight, maybe she's not good in fighting but she's very good in healing etc.
mayuri is not that weak, and he still he can stand a chance against other captains. he'll use his intelligence to beat them..
the weakest captain for me is komamura, he's just big, all he has is strength, and his bankai is just a big monster..
maybe all captains have weaknesses in different ways..

Kurotsuchi Mayuri just I dont like him . And I think Kenpachi is the most powerful one.You know he is the only captain that can not use bankai.If he can ....
It's good for him to beat the new enemy. maybe bleach 485 captain will appear
Im not sure who is the weakest one but I think Yamamoto should be the strongest one in Bleach manga...
I THINK YOU SHOULD ADD THE "FIGHT" WORD IN THE TITLE OF BLEACH MANGA.
JUST LIKE YOU SAY, EVERY ONE HAVE WEAKNESSES IN THEIR DIFFERENT WAY, BUT THEY ALSO HAVE some good at things in their different ways.
all captain is strong,weak captain was already dead like Tousen Kaname
I'd say Toshiro is the weakest just because his power hasn't full matured yet. Hyourinmaru has the potential to be one of the most powerful zanpakuto out there but not until Toshiro can full master it's power. For now. It's funny but you can tell the strongest characters in Bleach from how often they fight. The stronger they are the less they fight. The exceptions being Kenpachi and Byakuya, they are very strong but fight quite often. But the Head Captain, kyouraku and ukitake rarely ever fight seriously and never at full strength. Hell they won't even show their bankai in emergency situations and these are really the strongest characters. I mean Kyouraku wouldn't even show his bankai against Stark which would have been the time to pull it out.
Most situations could be solved if the stronger fighters would stop being lazy since usually when they fight they kick ass easily.
