Hopefully besides those you mentioned--Ryan Russell, Dylan Reese--and Corey Potter (who was on a minor league contract). I've heard off and on that the Rangers might be interested in signing Artem Anisimov as well.
From what I understand Russian prospects come over all the time. The only reason there was a problem with Malkin is that he was such an important player to Metallurg Anisimov isnt exactly a major contributor to his Russian team. I may be off but this is how I understand it.
O haven't heard a thing about Anisimov after the draft. Leading up to the draft there was lots of talk about him. Some guides(Redline in particular) ranked him at 20 or 21st. I think Young Guns had him up there also. When I saw him fall off into the 2nd round I couldn't believe the he was still there when it was the rangers turn to pick. Since then I haven't heard a word about the guy.
