I like that Silayev has better ceiling than Dillon and even if not from the start but with time he will make our defensive line better, especially if he will find more offense in him and some dogsh1t to present it for his opponents.
Luke, Simon and Casey will develop their game too. And its not like Luke is some kind of young player with potential, he is playing like a star defenseman already. Just a couple of steps for being elite.
If Orlov is in a good relationships with Spartak, he can develop his game fluidly and if he will do better, we can use Siegs until the end and Silayev will adapt too. I believe Fitz doesn't want to have a couple of defensemen rockies in the roster. Looks like he isn't ready even for one rockie now.
I think for now 7th defenseman is just a bench role. I believe Fitz will call Nemec, Casey or Misyul if he will need to replace someone in injury case. Defense is really great now.
Fitz(his scouting groupe) made huge job in scouting defensemen, would be great of ge will start to scout some forwards with offensive potential. Steven and Even are doing better job by their own when Steves first job was making people in his bar happy and writing his book. That was literally the third gig in his life, but our scouts can't find forward when scouting is their full time job. May be because everything they did is trying to find good defensemen.
