Mirco Mueller is a big two-way defenseman with the potential to be the cornerstone of the San Jose Sharks blue line for years to come. He skates well, but it will be a point of improvement going forward. He plays a technically sound game and is rarely caught out of position. He brings with him a shot blocking prowess, and an ability to effectively use his size to clear the crease. Mueller's offensive play is limited he is a work in progress in terms of puck skills and shooting/passing, but he has a good first pass that can jump-start the transition game. His calling card to this point is his defensive reliability.
Mueller will look to see consistent ice time in his second season with the Sharks in 2015-16 and should benefit from the presence of veterans Marc-Edouard Vlasic and recently-acquired Paul Martin in the San Jose lineup. With the coaching change after last season it will be interesting to see the approach the organization takes with the 20-year-old, whose long-term development might be better served playing a larger role at the AHL level. Long-term Mueller projects as an effective, shutdown top-four defenseman capable of playing in all situations and logging significant minutes.
