This is a very optimistic view. Cholo doesn't look like he has the tools to be a top pairing D guy. And Seider has never played on North American ice, form a league that has never been known to produce elite talent (Seidenberg, and Ehrhoff are the only two major players to come out of that league). The chances that they both hit as top guys is near 0. Though I am much more hopeful Seider will become a #2 defensive d-man than I am that Cholo becomes more than a #4 PMD.
Uwe Krupp was awful for us, but otherwise pretty good in the NHL. And not a million miles away in terms of profile.
