People always say this, but what did it mean?
Did it mean, will do nothing in first two years and be a question mark entering year 3 or did it mean, "won't be a plug and play star like some others taken that high" ?
I have a hard time believing that when he was drafted that the Kings thought that by the end of year 2 that QB would be playing at a sub-replacement level and be scratched in the playoffs with lots of uncertainty entering year 3. Now granted, a lot of that is the Kings own doing with the bizarre development choices but I think the longer development thing really just meant that he certainly wouldn't be a McDavid and wouldn't even be an Eichel. Which I think all of us accepted and were fine with.
I can't speak for everyone else, but for me, had QB played D+1 in the NHL in a red-shirt year (which he almost certainly does if he's in another place), struggled a lot that first year but gradually got better to the point where he was showing serious signs of growth and potential by the end of D+2 (similar to the Jack Hughes development curve) there isn't as much concern here.
And to add, if he truly is that big a project when do you start to see tangible results that warrant the draft capital used on him. Is it this season, the season after, the season after that? And at what point is it fair to question whether taking such a project was the correct choice. And again, I don't see him as that kind of project, but maybe some do and I'd be curious their answers.
