Thats the cutscene when you go with the big agent.
If you stay with your friend, you get nike and jordan around playoff time. You can get sprint but probably not sprite. Most people haven't gotten kia with him. It's probably more stuff but this is all I can think of. I'm debating on whether or not to go with the big agent or not. I would love to wear adidas but they only have 2 good shoes that I really like. Nike has more shoes I can wear but I've always gone with them. Jordan is in the middle. I'll definitely leave my agent if everything in the team shop is free when you sign with adidas(probably isn't). If not I think I'll sign with adidas. Idk its 50/50 for me.
