It's not an excuse, it's a reality.
There are only maybe 15 forwards total on planet Earth that can carry a line of dog **** and still perform.
That would be McDavid, Crosby, Malkin, P. Kane, MacKinnon, Hall, Ovechkin, Matthews, Gaudreau, Tavares, Kucherov, maybe Kopitar, maybe Seguin, maybe Stamkos. And after that it gets really thin.
Leon is not in that group but he is still immensely valuable and the Oilers are very lucky to have him. But he is of the tier below that needs help on his wing to produce.
That doesn't make him a bad player. It means your management needs to understand they have to have adequete talent levels. There is your problem. Not Draisaitl.
Draisaitl will be a 70+ point power center that beasts in the face off dot and has great vision, but to unlock that you need to give him something reasonable to work with.
Don't totally disagree but I would counter again with this whole driving line business is nonsense.
To me, each and every one of those players need Complimentary help in the success they enjoy.
For this point, you're right that Leon does too. But it's not as if he can't be productive at all and play his style of game without it.
If I use your theory, I would say that only a select few in the history of the game could 'drive without help. Conner, Gretz, Mario, etc among them.
