Scrivens had a 91.6% save pct after arriving in Edmonton.
Fasth similarily had a 91.4% save pct.
If we assume they'll split time in net roughly equally... that's a projection of about 91.5% going forward.
Last season the Oilers had 2686 shots against and let in 257 goals (plus 10 empty net goals against and an extra 3 goals against for shootout losses).
Assuming the same number of shots against... Scrivens and Fasth should let in ~228 goals vs 257 last season. Lets assume the empty net goals goes down as well by a similar pct... so say 9 ENG this season.
Throw in 3 more again for SO losses... total projected goals against... 240.
That's 30 better than last season's total of 270.
Now onto the offensive side...
Last season the Oilers took 2208 shots and scored 199 goals (includes 8 EN goals for) (+4 more for shootout wins) for a total of 203.
They scored 199 goals on 2208 shots which is a shooting % of 9.01%
That's actually a better scoring rate than the league-wide average of 8.89%.
So if they take the same amount of shots as last season... but regressed to the league average last season of 8.89%... they'd score 196 goals + say 1 more empty netter (because they are better this season
.. and 4 more again for shootout wins.
Projected total goals for of 201 goals this season.
So 201 for and 240 against. Still a net deficit of 39 goals... probably keeping them in contention for 14th (or 13th at best in the West).
Of course they could turn the tide after 8 years of being outshot... and actually lower the shots against and raise their shots for... which obviously would alter the goals for/against projections dramatically... but I've believe that when I see it after watching them outshot BADLY for 8 years in a row.
