Thing is, that is how the expansion draft was designed.
I hate Bettman, but he was wise to be the first of the major North American sports leagues to put a team in Vegas. The problem was that a middle American desert city isn’t exactly a prime hockey market, so they had to find a way to build a team that could be successful quickly. They did that correctly. The fans bought in.
Looking forward, other teams are better stocked in their farm systems. But they got the cup and hopefully earned the fan base.
