Who do you think starts jump serving after spring nationals 2013
Personal head cannon/speculation I think what let’s date tec beat Karasuno during the inter high prelim final is the fact that they now have super strong serves (as seen in the training match pre nationals) and they become more consistent and powerful but what I think happens is
Kogane starts jump floating! Yes the player in their team that’s the most wip actually improves a lot with pure volleyball feeling over the jump from nationals to Interhigh final and is able to jump float serve (but he’s still not super accurate, think Yamaguchi in s1 level of serve development) he misses fairly often but can produce a good serve that applies a lot of pressure to Karasuno along with futakuchi and aone scoring a lot of points on them with jump serves
The reason this makes a big difference is because of the drop in floor defense from asahi and Daichi graduating and the now 3rd years ennoshita and Tanaka having to be the main non libero defensive anchors which makes their serve receive and floor defense weaker then before but I don’t think as a team they become worse I think they trade a drop in defense for more offense
What I think happens after they lose though is
Tsuki gets inspired from the kamomedi and now after seeing kogane jump serve to ask Yamaguchi to teach him how to jump float!
I also think if he doesn’t become a regular after nationals, Yamaguchi converts to wing spiker and becomes a regular after he improves his floor defense and as a boost of height I’d imagine he also becomes taller so he is also a good front row blocker now.
I think by the time they play inarizaki in their rematch Karasuno is a much better team then they were year prior but still lose (barley) I’d imagine it being a very close match still after the Miya twins lock in and embrace their leadership as now 3rd years and exploiting the drop in floor defense that the previous 3rd years had. But I think ennoshita improves the most in pure ability along with Yamaguchi and we also get to see a tsuki jump float
I also think suna learns a jump serve around this time considering he makes it to d1 as a pro and it isn’t stated that he went to college so I’d imagine he became a good server and an even better blocker
I also think the reason Karasuno losses both matches against date tech and inarizaki is because of, serve receive. Which I think they drastically improve when the Karasuno first years become 3rd years
Thank you for listening to my head cannon yap🧍
