Two things.
1. Blake Lawrence is absolutely, 100% lying about the prevalence of these large deals. He has all the motivation to make people believe that a lot of athletes are receiving 7 figure deals, and only someone working for a collective will push that narrative. It definitely happens, at this point, it's still rare.
2. Your second quote from Caspino has been my biggest concern with these deals and I mentioned it in particular with the Texas non for profit scheme. If I'm a parent I'm not having my kid sign any deal that doesn't have an explicit quid pro quo attached. "I give you $1,000,000 you shoot 5 commercials and allow me to use your image for 3 years in all print advertisement." Any deal that says we'll give you this but you have to do some undefined duty later, is poisonous. The new era for compliance departments is protecting the student athletes from shitty deals. K-State, at this point, looks like they're trying to get ahead of this.
