mmm I guess that's true, though I was initially more focused on the fact that ES21 seemed more about team plays and trick plays as compared to KnB which honestly just felt like it ended up being a 'character overpowered' sports manga.
I think I'll go back to the point about taking things within context. Let's talk about the three sports manga we're comparing.
1. PoT = individual sport (somewhat team-based if doubles) -> this is why every player has supernatural skill
Being mostly an individual sport, PoT ends up as the ultimate 'character overpowered' sports manga because the battle is basically a case of whether your supernatural skill can beat your opponent's supernatural skill or not. It's not about tennis anymore, but mainly about who has the better usage of their supernatural skill.
2. E21 = large size team sport (individual can't really carry the team) -> this is why a team usually has at least two players with super skills
Due to the number of players and the way the rules are designed, you can't really just rely on one person's super skills to win the game. That's why Sena alone can't win everything for the team. If the line can't hold, they'll lose possession. If the quarterback can't throw properly, they'll lose possession. If the catcher can't catch properly, they'll lose possession. And so on. Thus, instead of straight forward 'character overpowered' sports manga, E21 switched things around by introducing A LOT of characters. Sena can run fast? There are Panther, Agon, Yamato, Shin to beat him. Monta can catch like crazy? Ikkyu, Sakuraba, Teruma are as good if not better. Kurita is super strong? There are many rivals in Gaou, Banba, Ootawara, and others. Therefore, the 'character overpowered' element is not as obvious, and we are also distracted a lot by the character of Hiruma who functioned as the brain (trick plays strategy) and also comic relief (with guns and pissing off opponents). But in the end, E21 is also an 'overpowered character' manga because Sena power up to beat Panther, Agon, Shin, Yamato, etc. Same with all of his teammates with their respective opponents. It's just not as obvious due to the number of characters in the manga which allow the focus to change from character to character.
3. KnB = small size team sport (individual can carry the team) -> this is why only few players have super skills (one or two per team)
Despite being a team sport, basketball team can be carried by one single player much further than american football. A good example is LeBron's Cavs years ago and Iverson's Sixers a decade ago. They might not actually win the championship, but they carried the team so hard with their super high level of individual play to the finals. If there's a case of 'overpowered character', it is much more obvious in a game of basketball. However, despite all that, it is still about basketball because support characters are playing normal basketball, and even the superstars in KnB aren't supernatural skill players like in PoT (balls not bouncing, balls returning to the same spot all the time, balls smashing the player to the wall, etc).
true. But my issue is more of a...let's say Kuroko and kagami were at level 50 before the training. after the training, they seemed to be lvl 80. but somehow, during the course of the match, they ended up being lvl 120. (lolwut)
Just like how Aomine went from lvl 70 to 125 after 'unlocking' his 'animal instinct'.
First of all, while I understand it's your own example and you're free to label the number of level you feel appropriate, I think it's a little misguided. It doesn't really matter what level the characters are at because what's important is whether your team can score more than the other team or not. Of course Aomine is being one of the best (if not the best) player, then he's super high level, and because Seirin is meant to win (due to them being the protagonist team), then Seirin needs to compete at around the same level as Touou. If you feel that Aomine is level 125, then it's normal for Kagami to go up to level 120 to compete.
But the reason why you felt that it was'too fast' is because you exaggerated Aomine's jump from 70 to 125, and thus, you feel Kagami jumped from 50 to 80 to 120 being super fast. Unfortunately, this is inaccurate, and I'll explain why.
If you look back at the manga, Aomine being 'in the zone' basically made him improve from 80% to 100%
If you believed his initial level is 70 (being the 80%), then Aomine's 'in the zone' level is merely 87.5 (100%) and not 125 (142% and this is your massive exaggeration)
If we now believe that Aomine's 'in the zone' level is actually only 87.5, then Kagami's level up during the game is only from level 80 (after USA training and at the start of the game) to level 85 (during the game and still lose) to level 90 (if Kagami managed to beat Aomine)
Once you put things into more proper perspective, powering up from level 80-> 85 -> 90 is nowhere near 'too fast', and it's actually very reasonable looking.
Somewhat off-topic but related to the current Aomine vs Kagami plot line, I remember about 3 years ago when I watched Nuggets vs Cavs and it was a close game. The last 2-3 minutes of the game, it was pretty much LeBron vs Melo just playing one-on-one. Cavs possession went to LeBron, Nuggets possession went to Melo. They guarded each other, and they just went back and forth like crazy. LeBron drove past Melo to score, then Melo head fake and took mid-range jump shot to score next. LeBron hit a three, Melo hit a three next. And so on. It was a crazy game and I remembered being in awe seeing how those two basically carried the team on their backs. In a sense, they were on fire, and it's somewhat equivalent to being 'in the zone' in KnB's Aomine/Kagami.
It's only chapter 130, weekly manga, so it's not yet (though almost) 3 years, yes.
I didn't want to nitpick too much, and while you're right that it's a weekly manga, KnB started in December 2008, and volume 15 tankobon was released in December 2011. So even if it was only 130 chapter, it was actually already 3 years. It isn't exactly 50 chapters/year due to golden weeks and/or breaks.
Oh and yellow, you aren't mad. I also want to see Kuroko to score. Maybe he'll score the winning basket someday hahaha =D
