Blue lock situation is not funny anymore, it is very sad. I personally know many animators from new episodes — and most of them are good animators, some are excellent... As someone who worked on one ep in 1st season, where situation with schedule was similar... I remember that I made several layout cuts with movement back then, nothing crazy, but all was transformed to stills. That was production focus, because there was no time and people to work on it on later stages (douga, shiage);
To all people who go and blame animators, harass and make fun of them, please stop, it is extremely not fair, they cannot change the overall situation and they are trying their best.
You can see that even though quality is affected by schedule, drawings are most of the time consistent and good. They know how to draw and animate well. They don't have a chance to.
So ultimately, all your concerns should be directed at Kodansha and Blue Lock production committee.
Not necessarily you can change anything (since its japanese corporations, they won't probably care) but audience can ask questions about massive quality drop with such popularity and revenue that those corporations on top of actual animation studio are making.
If you have read through this wall of text, thank you. I'm not expecting to stop this whole thing by one tweet, but still wort trying to get this message to some animation fans, I believe those are following me.
