Getting one late round pick that turns into a stud, and a few others who make the NHL but aren't anything special is in line with what expectations should be. Arguably we should have gotten a few more 4th liners but there shouldn't be an expectation that we get Gallagher level players from those types of picks. The same isn't true with 1st round picks, you have much better odds of getting a stud, and the floor should be much higher.
It's way too much of a coincidence to believe that the one time we drafted the right 1st rounder he just happened to be traded to a team known for being good on the development side.
Also development very much includes time in the NHL.
That's not the expectation for 12 years. Especially when the first round record is atrocious and every other teams studs is better than our stud with a late round pick. Ideally, we would have more than a forward with a career high 54 points to show for in 12 years.
And how about every other player we traded away/lost that became worse or didn't bite us in the ass? I'm talking about guys like Scherbak, Galchenyuk, McCarron, Beaulieu, Tinordi, Leblanc, DLR, Fucale...etc.
Cool, let's not pretend that every other team has perfect development, they are still getting way more out of their prospects.
