Having had a son that spent 5 years in the system I understand why players felt they were being taken advantage of. Coaches making millions, money they made the schools paying for all the different sports that didn't produce revenue, future medical issue not covered by the schools, not being able to major in what they wanted because it interfered with football, etc, etc. Not saying I agree with that but I understand it. The NCAA opened the door, the players just walked through it.
For example my son had to have his knee scoped last Friday to have bone spurs removed from his knee he injured while playing for OSU. He should have had his knee fixed the beginning of his Junior year but because the O-line was in such bad shape he played on one leg for two years before he had surgery after the win in the Alamo bowl against Colorado. He had calls from several NFL teams to sign as a free agent and have an opportunity to come to training camp but because he had surgery on his knee that would require a year of rehab to get back he missed his window. He also wasn't able to major in what he wanted because it interfered with football.
Don't get me wrong he had a blast, is very thankful for his time at OSU and has no regrets but he is not like some of these kids who think the world owes them something.
