It could happen but I don't think the supposedly several hundred thousand dollar offers ever take place.
Even if a booster or recruiter offered $600,000 for one kid to go to a school and the player accepted I don't think anything close to that would ever be paid for all the reasons posted before and more.
It's a fact Cam was shopped. Some say $180,000, some say $200,000. I think Auburn paid him and his family money but not anything even close to that amount.
I do think the improper benefits like a few hundred here, a couple thousand there, a deal on a car, a rent payment here, free clothes, a "date" on a recruiting trip, a smartphone there, mother gets a job here, dad gets a coaching job there and things like that are very common.
