Tvrdon has all the tools and physical stature to be a NHL power forward. He has size and he isn’t afraid of physical play or getting his hands dirty but doesn't play an overly combative game and is inconsistent. He boasts excellent speed, soft hands, great instincts and a scorer’s touch. He has scored consistently at the ECHL level but has been more of a lower line player in the AHL to this point.
Tvrdon spent the first half of the 2014-15 season with the ECHL's Toledo Walleye and has appeared much more ready to compete at the pro level since joining Red Wings' AHL affiliate Grand Rapids in January 2015. As with other scorers who dominate in Europe junior hockey and put up big numbers in major junior, Tvrdon is going through the learning process of developing the supplementary elements of his game. Long-term he projects as a lower line forward with some scoring ability at the NHL level. His game is still a work in progress to this point. He was placed on waivers for the purpose of contract termination in December 2015.
