Here's what I have so far.
It checks the recruits star rating then will roll a chance to randomly lower the stat(within a set range) based on how high the rating is. Numbers will have to be tweaked to try to flatten out the mid to low rated players of course. In theory it should keep all the high rated 3* players in tact mostly but lower the others. Right now it's set to leave all the 4 and 5 star players alone. Will need testing for sure.
