Austin was drafted into the league by the Rams and there have been concerns that he might struggle with his attitude off the field.
However, the decision to allow his mother to look after his finances will be encouraging for the franchise.
"One thing I learned was just make somebody else the bad man and that is what definitely I'm going to do as far as the money situation," NFL.com quotes Austin as saying. "So that definitely will be my mother, she is definitely up for the challenge and she is ready to pretty much tell people 'no.'"
"I definitely will help a lot of people too, you know, I'm not one of those type of people who forgets where I came from and just acts like I'm better than anybody else.
"But definitely there is a certain amount of times where it comes to a point where you have to say 'no' and she'll be that person that'll be dealing with it."
Austin was the eighth pick overall in the 2013 Draft.
