Dubinsky is a character guy that CBJ needs desperately. Anisimov is a decent 20-30 goal scorer, Erixson is a promising D prospect, and a 1st (will likely be high, but still a first).
The equivalent here would've been Pavs, Clowe, Moore/Petrecki, and a 1st.
Erixon is also the guy that refused to sign with Calgary and they had to deal him instead of losing his rights. Yeah, that's exactly the sort of guy Columbus should be trading for after it worked out so well with Carter.
Pavelski + Clowe is massively superior to Dubinsky + Anisimov. Dubinsky has basically zero value because of his contract, production, and injury status. He's almost a cap dump.
Also while Erixon is a good prospect, he's also a known discontent. Not something the CBJ need more of.
I refuse to believe that DW would be dumb enough to offer both Pavs AND Clowe for Nash... I don't see how Howson would not take that and run the second it was offered (assuming DW threw a 1st round pick in there as well)
