2013-14: Platzer began his second OHL season with the London Knights before being acquired by Owen Sound at the trade deadline as part of a multiplayer trade that sent Gemel Smith (Dallas) to London. In 66 regular season games between the two teams Platzer scored 22 goals with 14 assists and was -14 with 12 penalty minutes. Six of his 13 goals with the Attack were scored on the power play. Owen Sound finished fourth in the Midwest Division and lost to Sault Ste. Marie in a first-round playoff series. Platzer scored 1 goal with 2 assists and was -2 with 6 penalty minutes in five playoff games.
Platzer is a smallish center, but he does not let his size dictate his physical play. He is gritty and tough and is always the first one in the corners. Platzer has emerged as a primary scorer for Owen Sound in his third season of junior hockey and appears to be just scratching the surface in terms of his potential.
Platzer attended training camp with the Oilers before returning to Owen Sound for the 2014-15 season. Now in his first full season with the Attack, he has been among the team's leading scorers and has emerged as an offensive threat after being stuck in a mostly secondary role with a deep and talented London Knights squad for his first two seasons. Yet to sign an entry-level deal with Edmonton, he would re-enter the NHL Draft if not signed to a contract by June 2015. While he is still a bit of a project at this point, Platzer's improved offensive output suggests there may be more to his game than merely late round, lower line, minor league hockey potential.
