Of the three callups last night they all showed some good things. They had their troubles too.
Gryba's full speed skating and willingness to hit was welcome. He needs serious work on his lateral mobility, the quickness of his stops and starts and his puckhandling. If he does those things he could be a valuable 3rd pairing D. As it stands now he will be shredded by even decent NHL players.
Dziurzynski's skating is brutal for the NHL level (at least as it appeared last night). He falls down spontaneously, has next to no lateral quickness and his top speed is about average. HIs pucks skills are on par with Colton Orr if last night is any indicator. He clearly knows what his strengths are; he is defensively aware, plays north-south (probably because he literally can't move laterally) and will hit. I think he's a 13th forward, at best, on a good NHL squad.
Derek Grant toe-picked and launched his face into the boards in the laughable sequence leading to the first goal. After that he was solid. He has nice skating for a guy his size, can handle the puck and has some decent instincts (certainly a good sign in his first game in the show). He has, IMO, all the tools to be an NHL player. In a few years I could see 30-35 point, good checking center in this guy.
