I'm actually think that Denis is more physical and a better forechecker.
Not sure about the speedy part.
Agreed. Guryanov maybe isn't the most versatile player of the world, but at least he isn't one trick pony like Nichushkin was at the same age. And for me Guryanov is better overall skater, maybe even faster than Nich. His low IQ is only thing I'm really worring about. But I believe he still will be an effective player at NHL level, something like perennial 45-55 pts winger.
BTW he was truly dominant today against USA, real gamebreaker. I like the way he plays when it matters the most.
