Problem is that would mean Richardson needs 45 starts in the NFL to get where Jayden was. That's over 3 years of starts. That's a lot of losing and not likely to happen given how bad he is right now.
He needs to sit and work with a good staff. He obviously came out too early, but when you get that first-round grade, it's hard to stay in school, especially if you are not from a certain socioeconomic background.
