Also, we all forgot about Yamabuki. I don't know if this was in the manga or not since I didn't start reading until Nationals, but I remember Nanjirou saying how Yamabuki was crazy even during his era.
It wasn't Yamabuki, it was just the guy whos in charge of Yamabuki who Nanjiro is peed off with as Nanjiro was with a first seed Seigaku back in his days and it was Ryuzaki coach who said Seigaku had trouble beating Rokkaku (in that case Seigaku must be really bad or Rokkaku was amazing)
IF Echizen comes back, I can see Seigaku do well. I dont see much promise in the Freshmen trios or their subs, notably Arai. Fudomine would do well, but their front killer and his partner would just be classified as National Level, who although both won the First Round in the Nationals, lost to Makinofuji...EVEN if they were last years runner up. They should do well.
Hyoutei...somehow I don't see much in Ootori, who although has a super serve, lost to Hiyoshi, who doesn't stand up much either. Kabajii...how would he deal without Atobe? They do have over 100 pre regulars though...all got owned by Davide haha...
Rikkai... they only have Akaya as far as I know, and that isn't really enough. But since they won Kantou for past 15 years, they must have a good squad either way...?
Rokkaku will make it to the Nationals, HigaChuu looks like they're screwed without Kite threatening them without Gouyu, Midoriyama sucks, as does St Rudolph, And Shitenhoujii should do well with Kintarou and Zaizen...
