This book seemed to have more filler than the other two. But there was a callback to a volume I thought was filler so maybe it's just setting everything up for the last volumes?
Other thoughts
1. I'm really bad at reading stylized hiragana
2. The drawings in the basketball scene made me cringe
3. The bios are getting a little ridiculous now. Do we really need bio info on characters we haven't even seen/barely ever see?
