Way too many words here, very confusing.
If you just want to cut a guy, Brian Gibbons for me.
I don't see him fitting long-term in PIT and haven't seen enough to suggest he'll make it elsewhere.
If you are looking for trade value, Silfv is the only guy I can see other teams liking (he's had upside discussion).
Possibly Schroder, who I actually know very little about and can't grade.
I like Sceviour and Fraser - and I'd recommend keeping them on your team in real-NHL-value.
