For those of you who have watched him and Cole Eiserman together, who would you say is more impressive?
It depends on what you mean by "impressive."
Eiserman has more sizzle to his game and has that bring-you-out-of-your-seat type of skillset. He is fast, shows tremendous anticipation and a nose for the net, and he has a great shot. He can score from range with his wrist shot. He is also not afraid to mix it up physically and will throw a big hit on the forecheck, too.
Celebrini has good skills too, and a great one-timer, but he is a more cerebral player. Whereas Eiserman is a LW, Celebrini is a two-way centre who can contribute in many more ways, and some subtle ways that aren't "impressive" unless you understand why they are so important. They make coaches smile, but aren't likely to make fans cheer.
This is based on last year when they played 14U. I have not had a really good look at Celebrini this year because he was hurt for the games that I watched.
