OK
So let's look at a hypothetical, then, using this quote as the context:
Let's paste this sentiment onto the prospect pool of 2019. Looking at the past five drafts (2015,2016,2017,2018,2019), and assuming no one had been traded the equivalent would have been:
Since, of course, Meier was the only high draft pick.
Fast forward a few years, and your general point that fans were too optimistic is a fair one. The expectations around Chekhovich, Blichfeld, Gambrell, Balcers, Roy, Leonard, Chmelevski, Merkley, and Gregor were unmet.
But, at the same time, many of those prospects have shown themselves to be NHLers. Ferraro and Norris are top-half-of-the-lineup guys, Balcers and Gregor are firm NHLers, and Reedy, Chmelevski, Merkley, Weatherby, and Hatakka could still become solid NHLers. In fact, it's somewhat amusing how so many guys like Ferraro, Norris, and Weatherby really smashed expectations.
How are they defining "star"?
It's interesting because we kind of think of Merkley as a bust, but if you look at that 2018 class there are still a lot of players looking to establish themselves.
