The "discussion" only works if you are actually willing to listen to what the other side needs and start an offer with something that would resemble it.
Any "discussion" of us trading Draisaitl would have to BEGIN with the notion that you had a #1 or surefire future #1D++, preferably a right-handed one... that you were willing to trade AND who would fit within McDavid's prime.
The most important complementary building blocks for McDavid are, in order: #1 Defenseman, #1B Center, #1 goalie
Your #1D is too old and too expensive. Draisaitl is nearly the best fit for #1C in the league (only Matthews or arguably Eichel would be a better fit) and your #1 goalie is injured, too expensive and getting older. Talbot is passable, though not ideal... but you don't have an ideal solution.
So why would we trade one of those building blocks, which fits us perfectly... for an imperfect approximation of one of the other building blocks?
Thus... you don't have the assets.
