So let's say it is your son.
Why do you keep paying for him to play a game he clearly doesn't care about?
He has been playing long enough to at the very least know you shouldn't recruit D1aa players at D1a. You also said it yourself you gave him advice on how to knock of SIMS and turn guys green. Is his completely just ignoring his father? The recruits he signs don't even shown up in a search unless you look for D1aa talent.
None of this adds up. He has that many years playing, has asked other great coaches for advice, has a dad who plays the game and still can't even recruit d1a talent.
To me the biggest tell this is you using two accounts if the fact you still pay even though he hasn't learned or a thing or even listens to your advice. If it was my dad he would stop wasting his money and put it towards something more productive we could do together.
