theres lots of arguments,
i will say first and most importantly, WE ARE LUCKY WE HAVE BOTH.
Zibby while being three years younger, managed to pruduce one more point then silf did in the regular season while playing less games, he had a mean assist streak ( perhaps a future flash, of his playmaking abilities ? )
Silf, had 1 less point then Zibanejad BUT, everyone here knows the crazy amount of hockey this guy played while Zibby was out with a concussion, if you had a tv you could clearly see Silf getting flat out gassed, He had no stamina and that hit his production hard, Silf has one of the "great releases" a shot that is compared to Semin's (a 40 goal scorer, might i add ) , Silf was on pace for 17 goals in his ROOKIE season, even though he is 22 that is realy young, colin greening scored 17 goals last season at the age of 26 WHILE playing on Spezza's wing... Silf was playing on Zibby's and Turris's wing all season, not quite the same.
Both these guys are gonna get better, and you cant compare these two, because, one is Sniper Winger and the other is a Playmaking Center,
a little of topic.
Those who are not putting silfverberg in their untouchables list should be ready to eat serious crow very soon.
