Vejmelka is a big, 6-foot-3 goaltender who tends to profit from his size and uses it well in the net. His saves are not the most acrobatic, but he does a great job of keeping the puck from crossing the goal line by not quitting on a play and getting himself in front of second and third chances.
Vejmelka attended prospect camp with the Predators before returning to the Czech Republic. He will compete with veteran Robert Kristan and 24-year-old North American import Brandon Maxwell for playing time with HC Dynamo Pardubice in the Extraliga and could be loaned to a second division club for at least part of the season. He has the tools to be a successful NHL goalie one day but as with any young goaltender more will be known about his potential as he sees playing time at the pro level.
