Gaborik is an interesting comparison. He is UFA after next season, making 7.5 million. 31 years old, 27 pts in 48 games this year, 76 pts last full season. He was traded for Derick Brassard, Derek Dorsett, John Moore plus a 6th rd pick in the 2014 draft.
Vanek, 29 years old, is UFA after next season, 7.1 cap, 6.4 million in salary. 41 pts this season, 61 pts last full season.
They look fairly comparable - Vanek is a little younger. But I certainly can see Poile giving up similiar assets to get him like Columbus gave up for Gaborik.
