It would have been Portzline, and something he reported probably several months after the initial expansion draft reporting. Initially it wasn't publicly known exactly which of the draft picks was for taking Karlsson and which was for taking Clarkson. From Vegas' other deals you could surmise that Clarkson cost about a 1st, and Karlsson therefore cost about a 2nd.
What if.... the "value" of these 2 players was ABOUT a 1st and ABOUT a 2nd, and the combining of both players into one trade is what "evened" up the overall "value"??
