Or maybe I watch them, and this is my opinion of those players. Maybe it has nothing to do with bias, but actually an opinion.
The rest of your list aside, Josh Brooks reeks of an over-reaction to a D2 season. I think this is a good example of the flaw of the eye-test.
Sure he looks amazing to you, anything less would be a massive disappointment. Prospects shouldn't be sent flying up the list for dominating in their 19/20 season. Its not surprising he didn't continue to dominate when he got to the AHL and returned to playing against guys who are older than him.
I expect him to struggle next year and quietly slide down your list. Which isn't to say he can't be a good prospect. 13 is just an over-reaction in my mind, so I'm not surprised you're getting blow back.
Addison, Woo, and Smith all had more productive D1 seasons than Brooks did. I wonder if you'll have room for all of them in the top 15 next season when they invariably dominate the 16 year olds they line up against?
