I'd have him about 14 or 15. Guys like Burns have always been overrated, guys say players like Carlsson can't play defence, watch Burns play, it's a complete disaster.
With that said, this list is 100% invalid complete garbage horseshit when I saw they had f***ing Shea Theodore at 20. The worst player in the history of the sport I have ever watched try and play defence. I will repeat, I have watched hockey for 2+ decades and there is no player in any league who I have ever watched that plays defence worse than Shea Theodore. The guy makes Michael Stone look like Lidstrom in comparison. Theodore is a forward who would make the Kostitsyn brothers look like competent defensive forwards. He is the most overrated player I have ever saw.
