Few thoughts I had based off this post:
1. I don't really know how the cpu implements gameplanning or if it's even used. I would hope it is otherwise that is a huge advantage for the human player.
2. All my sims were based on the sim engine stats. So if you put up ungodly stats that will obviously skew the results in the humans favor.
3. Improving weekly or every few weeks as the human player will most likely give you an advantage to gain more XP then the cpu has. This is because you are improving your player quicker which would allow you to get better stats in game and gain even more XP and this could go on exponentially. A simple solution would be to limit yourself to end of season progression or at least half season.
4. Attributes are quite expensive this year. This is a good thread about how each year after age 26 things go up by a lot:

5. After all these sims I've done I have noticed a trend. Quite a few of the players that end up 99 ovr are between 3-6 year pros. So this goes along with the 26 year old thing and if a player is good he can get really good really fast. Also the fact that around 27-28 is when regression starts to happen.
