You've misunderstood what i am saying. The game has a mechanic that assigns skill points based on the actions the player performs. What i have suggested is merely a mechanism that gives a slight chance of a player picking up those skill points quicker, and a very slight chance of picking them up more slowly, to reflect the different skill levels. Not every young kid makes it.
The human player's ability will still ultimately determine the result.
Also, it would be a dice rolled each time you start a career game, it's not like "sorry, you got disk 10987, all your career players will be crap".
And the skill points are picked up based on the actions you perform, so they're dictating nothing.
