The agents you get are based on the talent of your player. For example, if your player's overall rating is at least 84, you will get Dan Baker as an agent. When importing players, that RBs get better overall ratings, no matter how many Heismans or any other awards they have won. Your superstar's overall rating is based on your Heisman over ratings, that is then randomly altered slightly each time you import. You can retry for better stats. The interview after the mentor meeting determines some stat boosts to important stats for your player's position.
