Grigorenko deserves an 8 out of 10, he's a sniper type of player that plays a gritty game, will he make an impact in the NHL? that all depends on his recovery from his car accident, the thing about this guy is he has the heart and desire to play hockey, he told one of Detroit's Russian scouts that he will make a come back and he will be better then his old form, I have faith in him and somday this kid will make an impact in the NHL, he looks like a top line sniper for the future Red Wings team, the way he played in last year's WJC, he looked a lot like an Alexander Mogilny with grit, I'm not saying he'll be the star Mogilny is, but he plays that style.
Hudler on the other hand does not deserve an 8 out of 10, 7 is more like it, having said that, I think Hudler is a bloom or bust type of prospect, at this very moment he's playing extremly well at the AHL level and he's putting up a lot of points, but his size does't help him at all, and he shies away from traffic, but the good thing is he reaks with talent and he also has the desire to be an NHL player, I think Hudler will be a second line impact center for the future, he's a gifted playmaker and should have a bright future in Detroit, if I would compare his style, I would have to say that he looks like Igor Larionov (NHL Larionov, not young superstar Larionov).
As for Detroit's future, it looks bright in my opinion, they pulled off few steals in the later rounds, Datsyuk, Zetterberg, along with Grigorenko, Hudler, Fleischmann, Filppula, and so on, these guys seem to be a fine group of youngsters up front, on defence we have Fischer, Kronwall, Bykov, and Meech which makes a solid defencive core, in net we have Howard and Liv who both have NHL #1 goalie upside, so overall I say the future looks pretty solid for the Wings, few keys are missing like adding a Power Forward, and maybe another top 4 defenceman would seal the deal
