Pronman basically states at the top that he prioritizes high end prospects which essentially means he values Oiler tank and draft high prospects rather than developing low end 4th line replacement players of value that ensure bottom pairing players are not over paid.
I've never been impressed by his work. To me, outside of evaluating how a player performs against his peers, he has little insight or evaluation about how well their skillset translates to the NHL.
The hardest thing for a middling NHL prospect who excels in junior is finding a role in the NHL. Moving from a 1st/2nd line junior player to a 3rd/4th line NHL player is a mind warp. It's 99% mental. They all have the physical skill, but it's being able to retrain their mental abilities to perform a different role for a team.
He provides next to no insight on this.
Shane Malloy's book, The Art of Scouting Details some of this, but its the tip of the iceberg on being able to evaluate how to evaluate players on transition skillsets between professional and amateur hockey. Hockey as an industry in still way behind in the training, developing, and fostering the mental aspect of the game compared to other sports.
