I don't think that the vast, overwhelming majority of Rangers fans would care about anyone other than Kakko. I would wager that if you went into MSG at the end of last season, maybe 5% of people would know who Rykov was, or (pretend he was our property) Adam Fox, or even Kravtsov. They would probably be like, "Oh he's that Russian guy that's gonna be good, right?" Probably 25% would know Shesterkin, because he's been around for years now. And then of all those people that knew anything about any of those guys, a tiny amount would actually spend any time trying to watch these guys play through a potato controlled by a monkey at Traverse.
HF posters are a different breed. Fanatical. ESPECIALLY about prospects. But, even most fanatics outside of here and a couple blogs aren't going to watch to see Jake Elmer, Nico Gross, Adam Huska, Shwan McBride, etc. They may check it out for a minute to see Kakko, but as soon as they realize the viewing experience sucks, they'll be over it.
I just don't think there's much interest.
