It is very dangerous and tricky to argue that anyone involved in a purely voluntary arrangement is being taken advantage of. Quick question, would you want your son to be a D1 football player if you knew they would never make an NFL roster? I would without hesitation. In fact, I would spend a lot of money on training in the hopes they could be a D1 athlete, and the country is filled with people who feel the same way. I don't even care about the scholarship money. I know all the economics of college football and I wouldn't feel taken advantage of in any way.
My son, and I'm guessing yours too, would be academically and mentally prepared to take advantage of his education as much as possible. And again, people love to twist this conversation from what it is. There isn't a question as to whether or not there is value in an athletic scholarship. The question is if the value of the scholarship alone is adequate when viewed next to the piles of money the universities, coaches and networks are making from the labor of those players who also aren't allowed to profit individually in any way. Name me 1 other situation where someone is not allowed to profit from their talent (excluding illegal activities). Some kids are prepared and understand the game and take advantage of the opportunities to set themselves up for the future (Christenson, Myron Rolle, etc). Many many others aren't and those kids are chewed up and spit out with nothing to show for it other than a few years of worthless classes under their belt.
