I have seen 15-20 Lias goals this season from various leagues and the WJC's. I don't really think you can distinguish which is which, they're all scored from the same place in mostly the same situations.
I don't know about his upside and how it will translate into the NHL when he's in his prime, I simply have't seen him enough. What I do like in my limited viewings, is how he's a puck magnet. That's an inherent ability that's not really taught. If he can work on his skating a bit, I won't say the sky is the limit, it isn't, but there will be a lot of Anderson jersey's @ MSG.
