What we also know, is it isn't critical to look good defensively, just to win those minutes, which has happened quite a bit.
When you are a +12 like Rielly and Brodie were in 21/22 (regular season) or +4 like Rielly and Boosh were after he was acquired, you are winning those minutes. Or nine goals for, two against, like Rielly and Schenn were in the 22/23 playoffs. Rielly and Boosh won their minutes last year too in the playoffs.. four goals for, one against.
Ultimately it doesn't matter if you aren't great defensively, it matters that you are winning your minutes.
