Kessell played against the world's best competition (for his age) on the "small rink" in the Ralph and funny, he did just fine.
Anyone who thinks the small rink is suddenly going to make him lose his game is deluding themselves, IMO.
How good he will be in college does remain to be seen, but I think there's no doubt he's going to be a top player for whoever gets him. I'm hoping our D can play him tough and give him little space to work. We'll see.
