These are quite the rumors, sources?

I don't think the Hawks do this. Murphy is worth more then a late 1st which you recognize by adding Bryson, but the only reason the Hawks would move him is to free up space for a logjam of young players/prospects they have on defense, not to add another one.

I agree with Chihawk. I think the value is fine however Hawks would likely rather than a middle 6 forward prospect or player than another D man. There currently 12-14 players with contracts that have at least 1 NHL game between NHL and AHL rosters for Hawks. Don't need to add anyone else.

Which are rumors?

Caps say no, can get better Vanacek deals elsewhere.
