Not sure how we take the salary back, but seems pretty decent, could then look to buy out Erickson next year.

Vancouver could get more for their cap dump services

why would Vancouver take on another long term contract that is longer than LOUI's especially one with a NMC meaning they have to protect him during the expansion draft. they already have to protect Myers and Ferland(NMC), plus probably Horvat ,Brock,Miller,Gaudette. they're not going to want to add another NMC for an over the hill player. unless Ottawa takes LOUI to help meet the salary cap floor the Canucks might as well keep him and if he gets picked in the draft great(they can always sweeten the pot for that to happen) or keep him and his contract runs out in time to help resign brock or extend Bo.
Seabrook is not an improvement over Tanev(who is a perfect partner for Hughes) the second rounder isn't worth the extra cap and term compared to Loui
