Hell, for a long time they were almost instantly graduating them to the NHL too. Wilson never saw the miners, and Burakovsky played like 10 games in the AHL total. If anything, both of them would have actually benefited with some seasoning.
I'll never forget the first 4 years of Wilson and how he would have benefited mightily from playing big minutes in a lower league instead of the 10 minutes a night he was getting.
They started over cooking them probably with Lucas Johanssen, but that's at least semi understandable. They had a secure defensive core and he had injury issues. They then followed that up by drafting basically drafting only defense for the next two years (Geisser, Walfridsson, Maass, Alexeyev, Fehervary). The fact only one of those guys has graduated, and one is fighting with a 35 year old player who's only ever had the minimum contract is ridiculous.
This just isn't true. You can look for yourself, but high round picks were not spending very long in the AHL, especially after they'd graduated and played almost a full year in the majors.
