I think anyone here can see I've been very patient and answered most of your questions. Its not my fault that you don't like the answers.
You accused me of not having a handle on the Flyers prospects, and granted i probably don't follow the team as close as a flyers fan, i do try to follow all 31. I would say you have less of a handle on the Islanders that I do.
More importantly... I have no bias here, I'm neither an Islanders nor a Flyers fan.
Lastly, yes... Quenneville is 5'8. More and more smaller defencemen are making the NHL now, but granted he's really small. Do you really think there is a huge difference between being 5'8 and being 5'9 like Torey Krug, Jared Spurgeon, and Victor Mete? Do you think one inch makes it now impossible that he can make it? I don't. But on top of that he was the 6th defenceman on my islanders list. He was behind Noah Dobson, Bode Wilde, Devon Toews, Sebastian Aho, and MVS.
Your attacks are based on the 5th and 6th guys in the system.
The Flyers fourth guy was Hogberg, 5th at Walynuk, and 6th at Friedman. Just for perspective.
Besides that, its the high end of the system that is going to have the biggest impact on the rankings, not the 6th best forward, or the 5th and 6th best defencemen in the system. That is why when i originally gave my explanation, I did the top prospects in the system first... and then moved to depth defencemen and depth forwards.... but sure, lets argue Quenneville vs Friedman, when chances are that neither will have much impact at the NHL level, even if they make it. That is why the guys at the top of the system matter more. It is highly unlikely that any organization has 6 defencemen in their prospect pool right now, who will all be impact NHLers.
