I never said that I didnt believe in McDavid and Draisaitl. My concern (which you shared a few posts ago) was that it (along with Chiarellis struggles with negotiating) plays a role in how the rest of the roster looks in terms of the cap.
But you said that the McDavid and Draisaitl contracts will be a problem or that they are a part of the problem basically insinuating that they won't live up to their deals. IF McDavid continues to compete for Hart Trophies every year and Drai becomes a Kopitar level sidekick, these deals will actually look like bargains in 2-3 years as the market and cap continues to inflate.
My point is that the Oilers will always be playoff contenders with these two locked up to go along with Klef and Larsson locked up and Talbot in the fold and that should be cause for some happiness. The rest of the roster could be filler and they would still make the playoffs with that core. Make the playoffs and anything can happen.
Whether or not they win multiple Stanley Cups will depend on how Chia fills out the rest of the roster and how well they draft and develop. I do know that I'm more than happy to go to war with the McDavid/Draisaitl 1-2 punch for the next 8 years even if their contracts look like slight overpays today.
