@Sternritter M I believe it's not just because of the sudden overwhelming that Cang Du was defeated so easily. From the little details I've picked up, a Bankai is something the ordinary Sternritters can't compete with. Quilge Opie got mad enough to use Blut Arterie when Ichigo said that they were afraid of Bankais (and people like him generally get pissed off by the truth). After being hit by Suì-Fēng's Mukyū Shunkō, BG9 stated that after having done his analysis, he wouldn't have to use Jakuhō Raikōben (implying that her Bankai was better than other skill of his). Still, it's just my opinion.

And as for Komamura, he has received the pill. The SRDI managed to connect with all captains and lieutenants, inside and outside Seireitei.
