You don't think recruiters take age into consideration? They absolutely do. Do you really think that all of these people are pulling a fast one on top 30 coaches? Your argument is invalid. They look at EVERYTHING! Age, skill level, grades, weight, height, parents' weight and height, sibling' weight and height, etc... they will not be fooled by a holdback.
You are misinformed. Look no further than the commits to top 10 schools from the class of 2020. Many holdbacks in that group.
