I think that the Sabres will get there in a couple seasons. By that time, Eichel, Reinhart, Mittelstadt, Dahlin, and Ristolainen should be hitting their stride. They'll be supported by some late picks like Olofsson, Ullmark, and Malone, as well as Thompson, Guhle, Pilut, and hopefully Nylander. Sheary, Sobotka, Scandella, and Bogosian are all UFAs, if they aren't gone earlier. Imagine this shell:
Girgensons - Eichel - Thompson
Nylander - Mittelstadt - Okposo
Olofsson - Reinhart - ERod
Smith - Malone - O'Regan
x Berglund, Oglevie
Dahlin - Ristolainen
Guhle - McCabe
Pilut - Nelson
Ullmark, Hutton
Now add Asplund, Davidsson, Samuelsson, Borgen, and Pu to that group. Doesn't look so bad.
