That doesn't make him a top 6 player. People complain about having too many Coglianos already. But they want another 15 goal 35 point guy?
Not really the same type of player. He has good hands is more of a natural shooter. He's just below 0.5 PPG, which is basically what most teams #6 forward produces these days. On top of that he is 23 and a sophomore with time to grow. He's not far behind Silfverberg as a player overall. Half the year he is even better.
I remember in the WC last year, my dad would laugh when this german would deke around two Swedish defenders and set up a teammate to a nice scoring chance. You are selling him short. Rieder can be a 40-50 point winger in this league.
