OEL's contract is massively overblown as an issue. He and Chychrun are fine players who should both benefit from a quality head coach. They are not the problem.
Chychrun is 22 and a continually appreciating asset. His contract, age, and output makes him one of the most valuable D in the league right now. OEL will turn 30 this summer, has by far the largest contract on the team both in terms of risk and cash burden while at the same time being a rapidly depreciating asset. Given what $10m in cash bought last summer, I would delete his contract out of existence for free, if given the option, right now. The flexibility alone would be incredible.
OEL hasn't outplayed Hammer in his own zone. Not by a longshot. And even though Goligoski frequently passes directly to the opposition, I'd rate them pretty evenly. OEL used to be a true top pair defender that would score 15-20 goals while at least constantly driving the offense. Now? He looks like a total passenger. This is a player that got injured because he was lollygagging to a puck and didn't think Kane would play the body. He has had several brutal ass games this year where he's the worst guy on the ice, sometimes being almost unrecognizable, all while wearing the C.
It's fine to like him and hope he turns it around under a new coach, but he is objectively on the wrong side of the team building math. I think it's also completely fair to question whether this player is a part of the problem. Even if he's not, I don't see him as part of the solution either.
If he goes back to being a top 10 guy under a new coach, I'll be thrilled. It just seems incredibly unlikely at this point given his injury history and overall play trend.
