Right now I am thinking that it's the calling up he trade deadline that is holding back the Sabres from Quinn, Peterka and Krebs up for regular roster spots.
The only way to have these guys occupy regular roster spots right now is to waive some players. With the TDL approaching, I am guessing that Adams will be active and there are a number of Sabres who could draw interest - given the Covid situation, taxi squads, and the playoffs.
I believe that Eakins, Hinostroza, Hayden, Jankowski, and maybe even Bjork might draw some interest from other teams from among the forward ranks. But until then, I think the only way Quinn et. el will see AHL action is due to emergency recall. After the TDL, I think that these guys will get a chance to play regularly for the Sabres and then the Amerks again in the playoffs
