Don't be facetious. The point still stands when you think about trading Eberle or even Eberle + a pick in a trade for any defenceman of similar value. Eberle has the worst +/- on our entire team. He is a defensive black hole. He's a small, purely offensive winger. We have more pure offensive players than any other team in the NHL.
I will ask you again. Do you think we are a better team with Eberle or with a defenceman acquired in trading Eberle + acquiring Kassian?
Depends on the defenceman. If that defenceman is Hamonic, probably. If that defenceman is some 4/5 eastern conference scrub that 'could totally play top 4 here' than no. It's not an absolute 'are we or are we not better' it depends entirely on what the return is.
Frankly? No. I'm not sold that Kassian helps this team in
any appreciable way. He'll need a solid month - at least - to get up to speed. Look how long it took Eberle to look like himself after being out for only a month or two, and then factor in that Kassian has been out since March. We'll be healthy long before we could reasonably assess where Kassian is. This isn't a guy at the top of his game (which even at the top of his game is somewhat limited by his peanut brain) this is a guy that hasn't played since March, broke a hand and a foot, and spent the last few months in a rehab program.
I got my fill of reclamation projects with Cam Barker and Gilbert Brule.
