What was our record when Scandella was playing 18+ a night at 5v5 with Parayko against top competition and what is it now since he’s been moved down for Mikkola is imo the far more important question in regards to our record over that time span, not Perunovich.
Games 1-12: The team went 8-2-2 in the first 12 games of the year where Scandella averaged 21:35 a night. He was above 20 minutes in 11 of those 12 games and played 18:58 in the other. Perunovich wasn't with the NHL team yet and Mikkola played 2 games in this stretch (less than 12 minutes each).
Games 13-24: In game 13, Scandella plummeted to 15:33 of ice time and never hit the 20 minute mark over the next 12 games. He averaged 15:12 a night in this dozen game stretch and the team went 5-6-2. Mikkola had not yet taken over his vacated minutes and they were getting filled by committee (with Perunovich being the biggest benefactor at 17 minutes a night from game 15-24).
Games 25-28: Scandella got 20+ in each game and the team went 3-0-1. This was the stretch where Faulk was out. Mikkola also averaged 20 minutes a night in this stretch. Parayko and Krug round out the top 4 and then there is a big drop off in ice time to the 3rd pair. Faulk returned in game 29, Scandella is kicked out of the top 4 and Mikkola stays with Parayko.
Games 29-44: This is the sample where Mikkola has taken the top 4 role while Scandella is playing a bottom pair role. The team goes 11-5. Perunovich plays just 5 games in this window and the team goes 2-3. Perunovich is on the ice for 5 goals against and 2 goals for despite carrying a 90% zone start rate. The underlying numbers are much better than that (all in the 50s) but still not what you want when a guy is basically completely and totally sheltered. The team is 9-2 in this stretch in games where Perunovich isn't on the ice.
The majority of Perunovich's quality play came before Mikkola got his opportunity at the 2nd pair. Since Mikkola took that job, the team has gotten much better results running a Scandella-Bortz, defensive oriented pairing than they did trying to shelter Perunovich on the 3rd pair.
Again, I'm not saying that the team record is 100% on Perunovich, but he absolutely hasn't shown proof of concept that our best 6 man blue line includes him.
