Let me break down some numbers when it comes to player development. Commonality for player development is like this. Age 20 and 21 are the most common, more than half in total, age 19 and 22 are less common, age 18 and 23 are the least common scenario. Amount of training learned during these 3 years of development is ~35% of total. By the time players reach 24 0 0 they should be between 65% and 75% of their training. Difference is influenced by the development type. Although percentage sound small on paper it needs to be looked on from another perspective.
