The reason why people are talking about trying Ritchie in the top six is because, for all of his inexperience, he at least has real skill. Beyond MacKinnon, Rantanen, Mittelstadt, and Drouin, there is a really scary lack of raw forward talent on the Avs projected opening night roster. Who ELSE are you going to put on the second line? O'Connor? Colton? Wood? Kiviranta? We would literally be better off playing Girard as a winger.
Ritchie would pretty easily be the fifth most talented forward on the Avs. Giving him a 9 game trial is worth a shot, IMO, especially because aside from bulking up I don't think the CHL is going to be of real value to him this season.
