Rookie premiere

I know that you get a player on madden 23 and it somehow gives you stuff of the next madden. how does this work and what kind of rewards are given?

It’s like a regular promo, but as you go along in the promo, you can earn tokens that give you a head start on m24 MUT. The “head start” has varied over the years, so I am not sure what it will be this year. However, the other part of the promo is getting 99 overall versions of rookies (ones that didn’t get 99s in the draft unless they get a huge boost somehow).

These two news posts should give you an idea as to how Rookie Premiere might work this year (won't be exactly the same, but pretty similar):
