It's always a concern that Plekanec might wear down and I think that's a legitimate concern for this season. He played almost 24 minutes last night. One game sure, but he can't do that every night. Desharnais, at the moment, is not pulling his weight and I don't think (or know if) Galchenyuk is ready to carry a 17-19 minute load in the NHL right now.
Eller hasn't shown so far this season that he is capable either. With condensed schedule and back-to-back games this could be a problem down the road.
Eller has hardly been used at his natural position. Therrien can think what he wants about ES, but not using Eller on the PK is Pejorative Slured.
