Silfverberg is Ottawa's best prospect at the moment. I think him and Stone are going to be NHLers for sure, and both guys' have improved a ton since being drafted. Both also similar in that their only weaknesses are their skating. I wouldn't bother trying to compare stats between the two as their leagues are completely different, and in the SEL a prospect's situation differs year by year. Many people think both can one day be star or impact forwards in the NHL. Edit: another similarity is that they both have size yet don't play a heavy physical game.

Also, just to point out, they are only 1 year apart in terms of "hockey age".
