Even strength, which is where most people gauge line combinations on, Draistaitl spent 79.9% of the time with McDavid last year.

I'm a reading those percentages wrong or are you? It's late so it's entirely possible I'm looking at things wrong.
Faceoffs are an interesting thing, it's good that Leon took that many but it's a poor indicator of what happened after the puck was dropped. Wingers that take the dot usually revert back to wing immediately. I think you'd be hard pressed to convince anyone McDavid was a winger half the season because it wasn't unusual to see Leon played down low.
Your last sentence seems pretty anecdotal. You seem to be really stretching some facts and some anecdotes ("wasn't unusual to see him down low") to say he was a center half the season.
