Yeah. McDavid just had so many issues dealing with "distraction". 

He only won the Art Ross and probably will win the Hart and he led his team to the playoffs for the first time in years but yeah, totally distracted and wilting under the pressure of being named captain.

And yeah, the most skilled guy is never the captain in the NHL. That's why Gretzky was never a captain. 

Maroon is a UFA after next season. Oilers won't be able to afford to keep him and he will be gone.
