In order to round up their current roster, the Kraken are forced to pick a player from each team in the league, and in a recent article for the Seattle Times, Geoff Baker presented a short list of six goaltenders, six defensemen, and four forwards that he thinks will be on the Kraken's radar.
Of course, you'll find that some of the league's teams feature on this list several times. While several players from a single team can be obtained by side trades, the Kraken will only be allowed to select one player from each team through the expansion draught process.
