Eriksson's contract is close to as bad as Seabrooks.
Seabrook in spite of all the trash he gets here is still a usable 2nd pair and PP specialist. Possibly the 3rd year he is 3rd pairing guy and the last 2 years are bad.
After those 3 years where is can play and be a key guy in the room for that young squad the majority of his money has been paid and he becomes attractive in a trade with budget teams.
Eriksson is not really an NHL player now and won't be for the extent of his deal.
They are the same in that they will both have 'dead years'. Eriksson's just happen to be now and Seabrooks appear like they can be sold/traded.
It's a nice snake oil salesman pitch, but that's like us trying to sell off Eriksson for Boedker who has 1 year left on his contract.
Eriksson still gets top penalty kill minutes, still a savvy vet defensively, plus under former coach Willie Desjardins he got 5 powerplay goals, played much better for Team Sweden, except under coach Green he's been regulated as a checker. All you gotta see is his powerplay time on ice dwindle from Willie to the Travis era.
We can say the last two years of Eriksson's contract he can be a mentor for the young swede prospects in Ottawa.
Anyways, 3yrs > 5yrs.
In addition Eriksson starting next July 1st, has a 15 team no trade list - much easier to move, while Seabrook has a ironclad NMC for another 3 seasons - right through to the expansion draft where he has to be protected.
