Well, Gaborik was a superstar that rediscovered his touch, crushing it for the Kings from the time of the trade through the 2015 season.
2014 was Kopitar's last season of consistency.
Regardless, the team had key contributors that you only get through the draft or by trading high draft picks, highly drafted prospects or good young players.
The 2014 team had players that were acquired via trading O'Sullivan and a 2nd (previously acquired, along with a 1st, for Demitra, the team's leading scorer the year prior. O'Sullivan was considered one of the top prospects not in the NHL), Jack Johnson and a 1st, Simmonds/Schenn (Top prospect in hockey)/1st round pick.
Point being, Lombardi didn't just pick up a bunch of trash off the streets. There is a lot of 1st round pedigree on that team. Aside from the talent, there was a lot of intangibles as well, including going through 2012 and '13 together.
The current roster is nowhere close, especially when looking at the blueline. This is, again, why landing Hughes seems to be very important as the team needs elite-level talent in short order before #11 and #8 aren't the building blocks you think they are.
