To say this after Jason has had more than three months without skating in quarantine and minus at least four competitions, aka no first half of the season to actually attempt his jumps, is a bit much.Brown - He improves constantly which doesn't seem possible! I suppose the quad is just not mean to be, so I hope he nails the 3A always and forever. I love SOTA.
If you look at his quads from practice, even the not perfect ones, it shows how much he improved and how closer he is. Like Jackie Wong said, he is less hesitant when jumping and he URs much, much less (\not at all) in practice; so the improvement is there and he can only go up, but he needs... you know... an actual season.
So to say Jason Brown is incapable is not knowing how the human brain works. The human brain does not just get stuck. You get stuck when you quit, but if you keep practicing brain synapses don't just get stuck and you can only improve. You don't just get stuck or worse by working more and having more experience. And by practice I mean, again, real seasons. So as long as he trains and attempts quads in real comps, the possibility of landing them relatively consistent is very high. It has nothing to do with failing multiple times and definitely not with age.
You said it yourself, "he improves constantly". But he needs to be able to compete in a season that actually has competitions!
Now I will say this, without any quad he could beat a lot of the top men. He could beat anyone besides Hanyu and Chen without a quad and with his very high GOEs on triples. He choses to train and attempt quads and I respect him and wish he's successful because he wants it and not because I feel like he needs a quad to be great. He's Jason Brown, he's already iconic.
And may I add, the top and top-ish guys with quads fall a lot and pop a lot. Like, A LOT.
And off-topic, Jason's triples are better than multiple-quad-skaters' (for the very most part). Shouldn't it be the other way round? Just goes to show...
