Imo, it comes down to expectations and comparing there salary, there should be alot more expectations on Myers. Next time the Nucks, are on the PK and Myers is on the ice with a chance to clear - watch & see if he gets it out; good chance it will be a WEAK ATTEMPT and the puck stays in, like the last PK.
The expectations on Poolman is to be at most a second pairing and Myers is a disaster in his clearing or exiting attempts; otherwise, I agree he is playing well. Perhaps you are looking at Poolman a bottom pairng d and I am watching one of our minute eaters on d.
