Losing Thousands Of Nil After Winning Nation Championship????

Why is it when I start a dynasty we get loaded with whatever the base nil is (which isn't the problem) but yet when I lead that team to a playoff year or win a national championship, that next year I start with less nil???

Why in year one do I have 3k points to work with with California but then after I win the national championship in year two I have 1k to work with??

Aren't I supposed to gain nil especially after making the team better, making the playoffs, especially winning the national championship???

Why is it year after year the nil I start with every year(even accomplishing all my ad expectations) my nil total goes down less and less every year??

And it's every dynasty I do year after year, even after winning playoff games or the natty (clemson, lsu, kansas state, whatever the team is) I lose nil I go from 3k 4k to in year two or three after being successful to having 1k even most times only 8 to 7 hundred.

I can't recruit better and better as my team gets better and better by the year if my nil goes down significantly every year. I can't upgrade my facilities with only 850 nil. I can't spend and keep players about to hit the transfer portal with only 700 nil, mind you this is with elite teams too.

Fix nil gain I should not, in no world, lose multi thousand nil after winning playoff games and a national championship.
