I don't think we know the full story on this situation yet. The government does not, since its investigation is not complete.

The entity that "hired" Farve was apparently a welfare-money fraud. Farve has paid all (not most of) the money back. He and the government are arguing over interest and penalties. Farve has not been charged with any crime, he has said he had no idea where the money was coming from.

Given Farve's charity work, it appears like many famous and wealthy people, he was taken in by the fraudsters and used. He should have checked them out.

I don't feel bad for Farve, as you say, he has plenty of money. But I hope it will not his charitable foundation, Farve4Hope.

Bret and his wife's foundation had given more than $8 million to charity as of five years ago to disabled children in Mississippi and Wisconsin. After Deanna Farve got breast cancer, the Foundation extended their mission to include aid for breast cancer patients. Looking at the recent tax filing... that number is now probably around $9 million.

Farve has also done a great deal of free charity work for things like the Veterans Wheelchair Games. It appears his Foundation is a "fund raising" foundation that distributes the money it raises to other charities...

Frankly, he does not seem to be the bad, greedy person you paint him as. He does appear to be not as savvy as someone who has as much money as he does, should be. But then he was paid for his football skills, not his financial acumen.
