It's the bolded portion which has me going conservative. I'd be happy with some form of 5-4 record ("4" including both regulation and OT losses).
While the team does have more defensive defenders, when up to 1/3 - 1/2 your blue-line is new (Olli isn't new but he only played half the season and around 13 minutes/ night), I think there will be some growing pains even as the partners learn to gel with each other. I'd expect either Poolman or OEL to be question marks/ inconsistent, and if Juolevi takes on primary defensive minutes he might need time to adjust too.
Most teams have also shored up some weakness (e.g. Edmonton with Hyman/ Foegele/ Ceci/ Keith?; Flyers have more offensive and defensive depth on paper; Detroit with Suter/ Leddy/ Nedeljkovic...; Hawks with Toews/ Jones/ Fleury; Kraken are brand-new; Wild were one of two playoff teams from that list last season, and they'll be dangerous with Kirill the Thrill and Fiala). That being said though, with the new offense, Dickinson and Halak as backup, I think we'll be a tougher opponent too, hence an improvement from the 4-5 start last season.
