I think Dean Lombardi relayed an interesting story about that portion of the Draft. The Kings had Simmonds ranked higher than Moller, but were surprised that Moller was still available at #52. Most had Moller ranked higher; TSN had him #29 on their list while ISS had him #25.
So there was a debate at the table about whether to deviate from the list and take Moller at #52 and then Simmonds at #61. The thought was that Simmonds, undrafted the previous year, was an off the board selection and would be there later while Moller wasn't going to slide further. Some at the table (including Dean himself?) didn't want to chance it and wanted to take Simmonds at #52. But in the end they rolled the dice and got both.
Even if it's not with the Kings, Moller's progress could at least make him an NHL asset to somebody in a trade.
