I'm not certain how the big center would improve the Flyers other than add size to a mostly small team.
Antropov has long been criticized for not playing up to his stature, and for the first seven years of his career was a disappointment in Toronto.
Last season he emerged to have a "career year" by scoring 26 goals and adding 30 assists, but he was their top scoring option.
He's been decent this season as well, with 21 goals and 25 assists, but has been a woeful minus-13 -- not the kind of responsible forward the Flyers like.
His salary is affordable at $2.05 million, but it's not certain where he would fit in on this team.
The Flyers would have to trade a player of equal salary plus a draft pick for his services (Joffrey Lupul) and would probably be wise to look elsewhere for an improvement.
