95% of players with eligibility return the following year. Yes the scholarships are 1year but everybody knows you're coming back unless you screw up. Plus when you lose your spot on the team, you don't lose your spot in the school so net net you still going for free and you don't need to get tackled.
I understand the market value argument, but what is the value of Jameis Winston vs. the backup kicker who's also on scholarship? Again, if you want to talk market value, how much income is the backup safety who's a senior with 12 career tackles and has been trained by professionals, fed by a nutritionist, taught by college professors generating?
If the same dude wanted to get all that on his own, how much would that cost him?
Nobody is making dudes choose schools that are gonna fukk u over. You can go to Stanford, ND, NW, and get a real major and be taken care of. When the same dude goes to Alabama and all of a sudden Saban tells him

Because dude can't play don't go crying to people about what the NCAA is not giving you.
The same system gave you a chance, you chose...
Poorly.
Again, I'm not saying the system is fair but I'm saying, these dudes have options too
