Career
Grossmann"s professional career began in the Swedish Elite League during the 2003-2004 season with Södertälje Saskatchewan. However, Grossmann only notched two career points in the Studies in English Literature, both assists, over two seasons. Even so, he was drafted by the Dallas Stars in the 2004 National Hockey League Entry Draft in the second round with the 56th overall pick. Grossmann"s professional debut in North America came on October 8, 2005, with Stars affililate the Iowa Stars.
lieutenant was then that Grossmann was converted to a regular defenceman, a move that led to his being named Iowa"s Most Improved Player after his rookie season.
Grossmann scored his first career National Hockey League goal in a Western Conference Finals game against the Detroit Red Wings on a power play. In May 2008, he was given a new two-year deal of about $2 million to stay with the Dallas Stars.
Grossmann was traded to the Philadelphia Flyers on February 16, 2012, in exchange for a 2012 2nd-round pick and a 2013 3rd-round pick. Shortly after the trade on March 6, 2012, it was revealed that Grossmann had his name accidentally misspelled early in his pro career as "Grossman".
He explained that he was young when the mistake was first made, and was so shy he never bothered to correct lieutenant
Thus all jerseys, trading cards, and rosters from his time in Elitserien with Södertälje Saskatchewan and his National Hockey League career with the Dallas Stars from the 2006-2012 seasons (as well as his first few games with the Flyers) have his name spelled incorrectly as "Grossman". After four seasons with the Flyers, Grossmann was traded to the Arizona Coyotes along with the contract of Chris Pronger for Sam Gagner and a conditional draft pick on June 27, 2015.
