They have not been the same team since Voynov left.
Interesting to look at the series of events that happened in different places.
Gagne gets hurt, which moved Brown to LW, opening up a spot on RW, which was filled by Carter, who was acquired for Johnson and a 1st, because they felt Voynov was ready to take his minutes.
Brown stops scoring a year before his new contract kicks in, and Richards had fallen down the depth chart, resulting in Carter moving to center, so a winger was needed, and that guy was Gaborik. He goes on to have a great playoff, and since Brown was a question mark, they had to re-sign Gaborik.
Voynov gets suspended, but the team is coming off a Cup, and if you could just get another defenseman to replace him, the rest of the team is basically the same as the team that won. Even though Gaborik had a good year, Brown didn't, Kopitar didn't, Sekera got hurt, and they missed the playoffs, which sent the 2016 pick to Carolina instead of the 2015 pick, which I think resulted in them getting Lucic(he was what Brown was still supposed to be), even though I'm not sure Lombardi truly believed in the team after 14-15. What if Carolina wins the lottery with the Kings 2016 pick if they missed the playoffs?
To me, what happened with Brown, Richards, and Voynov is what's wrong with the Kings. It screwed with the cap, and it screwed with the roster. I think it's made Lombardi do things he wasn't planning on having to do. I don't think he thought he'd have to find a top 4 right handed defenseman during the window of contention, or only get 2 years worth of a player out of trading Simmonds and Schenn, or that he'd get zero good years from Brown's new contract.
