Really lovely interviews. Not only he's an absolutely extraordinary skater, he also seems like a really sweet guy.
But yes, he needs to develop more speed and power. Hopefully that will come with time. Also, having that many transitions will reduce your speed obviously, so that is something the judges should be taking into account. Much easier to build and maintain speed if you're just doing cross-overs.
I really really hope he can win US Nationals this year.
