Rinne has to stop the easy shots. The first goal was completely his fault. It was awful. He is putting this team in bad positions by letting in a soft goal nearly every game. His angles and rebound control and play of the puck are just not up to par. He has moments of old Pekka, but he is not the same guy. He makes too many mistakes for really the last 20-22 months. It began near the end of Lavy's first year with us, continued all last year, and is still happening now.
I think the point about system changes is solid. IMO he just doesn't handle fewer shots and more odd man rushes that you get from Lavy's system as well as he did Trotz's system. Some of that is common sense as any goalie would, but I feel like he's struggling even more than you'd expect someone of his caliber. So Rinne needs to be better for the team to have success beyond what we've seen so far, but I don't get the 100% his fault type of comments. For example, on the first goal Irwin was totally burned and provided no help. Yeah, Rinne overreacted and played it poorly from that point.
Same thing on the 2nd with Subban making a horrendous play whiffing on a check and unnecessarily turning a 2 on 2 into a 2 on 1. The only positive I can say is at least Irwin and PK made big plays that led to goals to somewhat offset those gaffs.
With all that said, even if it is 100% on Rinne, he's what we have and I don't see that changing anytime soon, so the only option is for the offense to pick it up and hope he can make an extra save or two per game.
