I think you would be surprised, although the ones I know are 4 year deals which surpass 7 figures across 4 years if they stay, not 7 figures per year. Each year they play they get x amount. Off campus housing for family and and flights for family are also now being included as part of packages. It's not sustainable. These are skill players (not O-line etc) going to top 25 programs.
And to think, Portsmouth once lost a title because they moved a family a few miles and gave the father a job at a local business in order to get the son to play football for Portsmouth H.S. That's what I remember about it. I'm sure BTC can fill in all the gory details and correct anything I said that's wrong, but I'm believe I've got the essence of it right.
