I have no idea if it's a good indicator, but for kicks I thought I'd see what each combination produces vs. their cap hit.
Based on their production this season, Draisaitl and Yamamoto are producing 38.99 points per $1M of cap over 82 games. Scheifele and Ehlers are producing 22.45 points per $1M of cap over 82 games.
I know - major holes in that, but it's interesting to see what your money gets you when constructing a roster, and how important value contracts are.
Anyway, I'm not convinced that two key players from a team that is supposedly deeper, yet performing worse than the Oilers, will markedly improve the Oilers. Assuming Puljujarvi and RNH come back, forwards won't be the issue.
