Whats the logic in "if he was still young he would've trashed them" thats total bullshit... Even Toushiro who's considered young is around 100 years or older

Being young as a captain usually makes you weaker, ever tried paying attention?
I would give examples to prove my point but.. not worth it yet
and OT: I think Zero Division serves as a failsafe for the gotei 13 so in theory they have to be stronger incase all the captains+commander get defeated but I hope Kubo never released any information on them as I find it quite a lame concept, but thats just me.
