Grubauer is a big, technically sound, calm goaltender. His strength is his ability to fill the net and utilize his quick legs to make seemingly impossible saves while deflecting pucks out of harm's way. Grubauer is also possesses an above average glove hand. Having played at a lower level of competition in his native Germany, and seeing limited ice time in his first season with Belleville, he is still learning to deal with the more sophisticated scorers and higher quality shooters in North America. He can sometimes be deked out of position or beaten by accurate shots - particularly in the top of the net.
Grubauer's full potential is a bit difficult to gauge at this point as he has been dominant on stronger teams but been less impressive playing on middle-of-the-pack or weaker ones. He had a less than stellar run as Kingston’s number one goaltender, and was sidelined in the playoffs due to mononucleosis. Long-term, Grubauer has the physical make up and natural ability to one day be a starter at the NHL level but his game is far from complete and he will have to work hard to reach that level. He may spend time with Hershey (AHL) or Reading (ECHL), where he’ll need plenty of time to develop. With the Capitals' organization seemingly filled with young goaltending talent, Grubauer's NHL opportunity might come with another club.
