If I'm not mistaken, Vancouver fans said Cole was fine but over played, would have been better suited with 3rd line minutes. He can also play both sides. I'd be looking to add another top 4 LD and pushing Cole to the 3rd pair with Valimaki.
Sergachev is an offensive dman with passable defense. There may be some upside in his defensive game, but by no means should anyone expect him to shut down other players/teams with any level of regularity.

Also worth noting that Cole even though being the #4 D by TOI in Vancouver, his average totals were around a minute less per game than the #4 D on the coyotes last season. So not only are you expecting him to continue to be over used, but he is likely going to need to play even more ice time in the top 4.
Hoping someone like Szuber is ready to make an impact this coming season, his +/- was highest on Tucson by a good margin last year and 2nd highest point totals for a D man. I see his ceiling much higher than Kolyachonok.
It will be interested what materializes in camp, Valimaki and Kesselring spent the 2nd most amount of time on the ice last season together as a pairing. I'm guessing that chemistry will be relied upon with a mostly unfamiliar blue line.
