From everything I've seen and everything I've read about Fallstrom he reminds me A LOT of PJ Axelsson, who was one of my favorite Bruins.
Hard worker, really REALLY high hockey IQ, good skater.
Uses his body and has a little more touch then PJ.
Could be a really good shut down winger with flashes of offensive potential. Adding him into the signed prospect pool along with Knight, Spooner, Khokhlachev, Camara, plus Payne & Griffith on the way gives us a really deep pool of forwards with a good mix of skill sets.
