I agree it's not a big deal if you get the right stop gap ... not any stop gap.
One of Dickinson, Shore, and Faksa will be ready very soon for NHL duty ... maybe later this year ... maybe the start of the following season.
I've been in the camp, and still am, that see's trading Eakin as an eventual necessity likely, but they won't do it without a plan already in place IMO. It would be silly with playoff hopes to cut out your checking line center and gamble that you'll get someone "good enough".
He doesn't fill a minor role. He plays in all situations, and he's an above average contributor in most areas. That's what makes him a valuable trade chip.
Honestly though ...it's the goalie. From a value stand point, it's a bad trade. I have to admit that's my hesitation. Give me Bernier 2 years ago over Lehner right now every day and twice on Sunday. If Bernier didn't cost a pick and player equivalent to Eakin, I'm pissed if that's what they're paying.
Goalies traditionally have low values, and Lehner isn't even a proven commodity, and he's coming off a poor season. I get he's talented and that's great. I wouldn't pay a single roster piece for that player though. The market is flooded with goalies. There's no need to overpay for an unproven assset. Give me Lack for a 2nd (rumored asking price) before I pay a dime more for Lehner.
I'd gladly trade Eakin for an upgrade elsewhere.
