Source: Stars wanted Brandon Saad

NEW YORK -- A potential deal by the Chicago Blackhawks for former Dallas Stars defenseman Nicklas Grossman never came to fruition because of the Stars' demand for 2011 second-round pick Brandon Saad to be included in the trade, according to a source familiar with the situation.

Instead, Grossman was traded to the Philadelphia Flyers for a second-round pick in 2012 and a third round pick in 2013.

Saad, 19, began the year with the Hawks after a strong training camp but was sent back to his juniors team, the Saginaw Spirit of the OHL, after playing in two games. The winger is already considered a top prospect in the organization. His inclusion in any deal was believed to be a "deal breaker," according to the source.

Grossman, 27, is set to become an unrestricted free agent after the season. He has five assists in 52 games this season for the Stars.

Hawks general manager Stan Bowman is on record saying he would like to add a defenseman before the Feb. 27 trade deadline. The Hawks entered play on Thursday tied for the sixth seed in the Western Conference but had dropped their last nine games (0-8-1).
