In the Florida series, all the goals in Game 3 were from secondary scorers (all gone now but I digress).
A whole bunch of non-McDrai guys scored in Game 4, the depth guys scored 2 of the goals in Game 5, they scored 4 goals in Game 6 and the depth guys scored the only goal in Game 7.
The depth scoring was actually pretty tremendous in the SCF, that was not the issue. The issue was scoring 1 goal total in the first 2 games of the series, none by the top guys, and nothing from them in Game 7 and Skinner letting in a soft goal on the game winning goal. The depth guys were great in the last 2 series in particular, not to mention the historically good PK led by the depth guys.
Now it's a new set of depth guys so we'll see how they do come playoff time but depth scoring was not an issue last year.
Don't get me wrong, the top 5 (McDraiman, Bouchard, Ekholm) did a lot of heavy lifting as all top guys usually do for teams but the depth guys weren't an issue last playoffs in the back half in particular.
I think the biggest detriment to the Oilers in the Cup finals was Draisaitl playing at like 50% capacity if even that, he could hardly skate and was a non-factor.
