This is the way I see it and for the record I do like to have your opinion.
Hoffman - Zibanejad - Ryan
MacArthur - Turris - Stone
Puempel/Prince - Pageau - Lazar
Michalek - Smith/Grant/Legwand - Chiasson/Robinson
Our top 6 stays the same whether Eakin is here or not, he isn't better than any of our top 6 players then the 3rd line has already showed some great chemistry and Pageau put up similar numbers to Eakin in what was his first real NHL season so there's reason to believe he will be able to put up better numbers next season especially with Lazar growing and Puempel adding a scoring touch to that line. The 4rth line is still very good. Michalek is better than a 4rth liner without a doubt, he could play the 3rd line also if ever Puemps/Prince isn't working. Then you have 3 options at the 4rth line C and let's be honest these guys play 10 min a night too. Not a fan of Chiasson at all but he can play a 4rth line role, I'd also like to see what Robinson can do.
So if we add Eakin all it does is that: (because the other players don't change, of course you can change the lines)
Puempel/Prince - Eakin - Lazar
Michalek - Pageau - Chiasson/Robinson
So basically you give less responsabilities to Pageau to give more to Eakin while they both provide the exact same thing. Smith has already put up 12-15 goals on the 4rth line himself and for all we know could do that next season, If not it's no big deal we have two other guys that can play that role.
Personally I though our bottom 6 was good enough last season and it will be even better next season with Lazar, Puempel/Prince, Pageau all gaining some experience. Lehner was a big part of the future in Ottawa and trading him for a very slight upgrade on the bottom 6 is not a good idea. If Lehner becomes a #1 (which I believe he will and most fans believe he will) then we'll have a guy that score 15 goals on our 3rd line to show for while we already had that. If you go through the draft, there's a chance you get a legitimate top 6 F or top 4 D and I'm aware that it's going to take 3-4 years but I'd rather get a player like these guys in 3-4 years than a guy we don't need right now since we alredy have a ton of guys that can play that role. Also keep in mind that we need to keep good drafting and getting good picks being a budget team because when all our young guys develop to their full potential theres no way we'll be able to keep all of them. In 3-4 years guys like Turris, Karlsson, Zibanejad, Lazar, Hoffman, Stone, Ceci will be making a lot more money than they are now so atleast if we have some high quality guys in the pipelines to replace the guys we won't be able to keep due to salary restrictions then we'll be in business for a long time. The Ducks are doing this also and they look like they'll be good for a hell of a long time. I'd rather go ahead and look towards the future than to get a slight bottom 6 upgrade if we don't need it.
