It was said that if there were more than 10 of them the SS is doomed, but it seemed that Yama could easily defeat ythem all by himself.
And... that's where the main problem lies. You (and a lot of people) take every character's word as fact without counting the credibility and/or knowledge of said character.
The one that said that if Aizen assembled 10 vastolordes the SS is doomed was Hitsugaya iirc.
The weakest captain made an assessment of the enemy power without even knowing the strength of his fellow captain. Captain do not show their power to each other (that was stated somewhere) and before the Aizen incident, there was no way a young captain would be able to witness the other captain's real strength.
Same problem here, you're taking what that show-off is saying as face values.
If only Kubo were half as clever as all that, I might think you had a point, but nothing that's happened in Bleach has even come close to suggesting that. Sure, the guy is boast, but Yamamoto was supposed to be on another level, so that he could even defend against him makes him on another level as well and he doesn't even seem exceptional among the other Nazis.
