I'd rather have either Ritchie or Comtois over Jones.
I don't think the Sabres need to add a ton to the NHL roster at forward right now. Maybe follow up a Ristolainen trade with a trade for Tierney or JPG out of Ottawa?
Buffalo has one of the most effective lines in hockey in Girgensons - Larsson - Okposo. Shades of that line with Berglund on it.
Eichel and Olofsson make a good line. So do Johansson and Skinner. Add in Reinhart, Vesey, Sheary as wingers on those lines, and they are effective.
That leaves a 4th line for Mittelstadt and two wingers. Or one of the Ottawa centers, for example. Fleet up Asplund, Smith, Thompson as necessary.
Imagine Ristolainen and Rodrigues for Comtois and Larsson. Then a 2nd to Ottawa for JPG.
Vesey - Eichel - Olofsson
Skinner - Johansson - Reinhart
Girgensons - Larsson - Okposo
Mittelstadt - JPG - Sheary
x Sobotka
Dahlin - Montour
Larsson - Jokiharju
McCabe - Miller
x Scandella, Gilmour
Drop Mittelstadt down to Rochester and maybe bring up Wilson or Lazar if Mittelstadt continues to struggle.
That's a really balanced lineup, with three distinct defensive pairs: offensive, defensive shutdown, physical. And the team still has Cozens, Thompson, Asplund, Smith, Davidsson, and Pekar coming at forward. With Laaksonen, Borgen, Pilut, Johnson, Samuelsson, and Bryson on defense. Then Luukonen in net.
