Dorofeyev had another good game. He should be in the lead for the starting spot.
Howden and Comtois line had a good game also. Comtois hasn't been anything special but he could be a fourteenth forward for 800k or so. With his size he could play third or fourth line in case of injuries.
Brisson could get games with VGK this season, he's had good moments, especially on the powerplay but I doubt he would get much powerplay time this year. But injuries can happen so it's possible. He does seem like a bright spot looking toward the future.
Thompson has looked like he could get back on track after his injury this season.
The preseason means something for Dorofeyev, Brisson, Cotter and Comtois (maybe Thompson also to get games in, but he will battle with Hill to start the year regardless) but not much for the rest of the roster, I'm not worried about any results.
