Before we were probably looking at Beauch or Barrie in the bottom RD spot (minutes would not have matched, but still listed there). Now we can comfortably keep EJ, Barrie and Beauch in the top4 without having someone play 3RD and get moved around a lot to pick up extra minutes.
Personally I would like to see:
Bigras - EJ (gives EJ a smart partner who skates really well)
Beauch - Barrie (Barrie final gets a damn good defensive minded Dman)
Zadorov - Tyutin (Zadorov gets his mentor)
To me the most intriguing part of the 2016-17 corps versus the predecessor group is the increased versatility.
Last year's ATOI:
Beauchemin - 25:05
Johnson - 23:27
Barrie - 23:12
Holden - 21:56
Zadorov - 16:56
Bigras - 13:21
This team doesn't have the talent to be so top heavy on the blueline, but now it finally has enough talent to have a better committee-style defense. Even though Holden ate up a pretty decent chunk of icetime and Beauchemin is due to get a reduction, presuming that Tyutin can perform admirably in a 17-20 minute role (ATOI last season at 17:35), and Bigras & Zadorov take on more responsibility, and all of a sudden you have 6 NHL calibre defensemen that can play legitimate minutes. Then you can move guys around to find the best fits for pairings.
That leaves us with Weircioch, Gelinas, and hopefully Siemens to compete for the 7 and 8 spots. It's kinda sink or swim time for Siemens. If he's in the running here, it means he's improved to the point to where he can at least play at the NHL level in a fill-in type role. What I like best about these three is that they all play vastly different styles, which means you can mix and match depending on who from the main six goes down.
Don't get me wrong, I'm extremely envious of what Nashville has on the blueline, but all things considered, given what this team has to work with, I think we should be fairly content going into next season.
