If the argument is that there are players from the 2016 draft who are even further behind expectations than Logan Brown... then sure.
But if you were to put the top 15 picks from that year into two groups - successes and disappointments - which group would Brown be in? The one with Matthews, Laine, Dubois, Keller, Sergachev, Tkachuk and McAvoy? Or the one with Juolevi, Puljujarvi, Nylander, Jost, McLeod and Bean?
I'm not saying that Brown cannot still develop and become a contributing NHLer. It's certainly possible (just like it is with Puljujarvi, Bean, etc). But based on what I've seen, I'd be surprised.
My biggest issue with Brown is that the problems and red flags he had going into his draft year are still the same problems and red flags he has today. He has great vision and hands, yes. But he still lacks pace, he still floats too often, he still loses puck battles too often. The frustrating thing is that those weaknesses are all a function of effort, and after 4 NHL camps, he still hasn't addressed it.
