According the NHL Trade Rumors, the former 1st round pick could be in need of a change of scenery, and it sounds like the Flyers have received multiple phone calls.
Frost is still just 23 years-old, so there could be some teams willing to give up a nice package to try to get Frost to reach his ceiling, which is still relatively high.
Frost has just 28 points in 101 career games, and things are not changing for the better in Philly, as he has just 5 points in 24 games this year.
