Nathan's skating is quite fluid. He telegraphs his 3A like crazy, but he's still young, and will get a consistent 3A soon.
And yes, he does remind me of a young Patrick Chan!
The 3A is a pretty new jump for Nathan. He had landed it once last season, but his injuries kept him from attempting it during the rest of the season. He didn't do a 3A at all during the JGP, so it's huge he brought it out for JGPF!
