You are probably correct in the long term regarding Doan, but often times its not how much talent you have, but rather how you compiment the players you are with.
I think most will agree that Tage Thompson is the most talented offensive forward on this team, so how does Doan impact him when they are playing together:
Tage with Doan: 1 goal every 16 minutes ES. Tage with anyone other than Doan: 1 goal every 18.7 minutes
That is actual goals, how about how well they generate chances? (expected goals)
Tage with Doan: 1 expected goal every 17.8 minutes. Tage with anyone else: 1 goal every 22.5 minutes.
Small sample size, but in the 65 even strength minutes Doan has played with Tage, they produce, and generate chances better than Tage with anyone else other than Doan.
Just like last year with Kulich and Tage...maybe it won't last, maybe it will, but it deserves a bit more time to find out.
