Yup, RJ is right, the Kings inability to find anyone to even challenge Kopitar until (hopefully) this season made Kopitar a victim himself.
Look at Benn and Seguin, they have been on legit cup contending teams who went to the WCF's back to back years because their organization was able to draft Heiskanen, Robertson, Oetitinger, Johnston and Harley and quickly get them onto the NHL roster where they were able to push Benn and Seguin down to secondary roles (where players their age should be). They were consistently picking worse than LA and yet they were able to quickly develop top of the lineup players despite having older veterans in place. And their one very high pick (Heiskanen) they put into the NHL as a teenager (without any AHL games) and he was an immediate impact player for all three years of his ELC, in his age 20 season he probably would have won the Conn Smythe had Dallas won the cup, in LA he probably would have been paying his dues in Ontario.
It's ridiculous to suggest that the presence of older vets was somehow blocking young players from being developed here the way they are developed almost everywhere else in the league. It wasn't Kopitar and Doughty that caused such dismal returns for high picks under Blake, it's a ridiculous developmental philosophy that drastically overuses the teams AHL affiliate for players who should be developing on the fly in the NHL (especially true of guys like Byfield and Clarke who never should have stepped foot in the AHL).
