I see more extensive quotes from Trotz about Raty on NHL.com. Some of these are new to me, so I figured I'd post them here:
"This guy is just a good hockey player."
"I've been extremely impressed with the player to this point," Islanders Head Coach Barry Trotz said. "[He's] quite mature. Has lots of game, high hockey IQ, he reminds me of a Zach Parise-type of player. He's got a really good motor, always around the net, very intelligent, wins his puck battles, has really good hands. What a great pick by our scouts. Personally, there's certain kids that you get really excited with when they show up at camp. A lot of times we get a kid at camp, we get excited, but we go, 'He has this hole and this hole. We're going to have to work on this.' But there's not that many holes in his game really."
"One of the things, when you're a competitive guy is that when there's a puck battle, that's where the game is won," Trotz said. "Can you win more puck battles? Can you get the puck out when you're under duress? Can you make a play when you're under duress? That's one thing that he seems to excel at. That's the North American-NHL version. It's easy to be really good on the rush, with time and space, it's hard to be a good player in tight spaces."
"I'm fairly excited," Trotz said. "We talk about who impresses you and what you see. To start, he's made a really good impression."
