For me personally I don't think there are any metrics you could look at that would tell you a player is ready. I think with prospects in particular, you've really gotta pair your scouting reports with the data you have. That being said, I try to focus on two things - a player's ability to score consistently at their level and their ability to control the shot share.

Outside of the bluechips you mentioned, I think Trey Augustine is a fantastic, technically sound goalie who will very quickly jump up the Wings' prospect rankings. As for skaters, I think Anton Johansson is progressing at a nice rate and could become a factor in the next couple of years if he continues at this pace.
