While all Boston Bruins’ eyes are going to be trained on James Hagens during the IIHF World Junior Championships when Team USA takes the ice, it’s another B’s prospect that is turning heads at the start of the international tournament.It’s 19-year-old Will Zellers, who was the last player added to the Team USA roster that’s starred with three goals in the first two games for the Red, White and Blue while outshining some of his more hyped teammates. The former third round pick has shown off a tremendous shot and release during the first couple of games, and it’s easy to see why Zellers has been scoring so many goals at the USHL, college and international levels over the last couple of seasons.
