The problem with that, is no team would probably not offer more than a B+ prospect for Campbell, or possibly better than a 3rd round draft choice....and yet, he is worth 8 times that....and he's been better than Quick all season.The numbers don't lie...they're not even far away, let alone close. It's Quick you trade. Campbell is better than many NHL starters right now and signed next yr for $700,000.
The Kings survive without Muzzin and Carter and they will survive without Quick. 2019; 5 years removed from last Cup. And all players from that team have slightly regressed to more than slightly regressed. All of them.
The worst trades ever made is dealing a player for 25% of his actual value. Dealing Campbell would be one of those.
