Now I may get flamed for this but I made a interesting comparison. Below are two links to two different youtube videos.
The first is a video of the kid Austin Tamagno, he is in a Green top and ended up getting 2nd place in 4:13 for 1600 meters ...

Now the next video is a pretty popular one, of German Fernandez running 4:00 for 1600 meters his senior year in high school.

I too, googled Austin to see if he was mature or young... and then found the race above of him running 4:13. I could not believe how similar he reminded me of German. He looks young and full of growth.
I am from California and remember seeing German as a sophomore, and this kid reminds me of him so much! just raw, and once German filled out look what happened. Of course its early to claim things... but this kid looks good.
