The league has the right to establish minimum requirements.

I'm not so sure about that. What makes the NFL different from the NBA which was forced to lower their age of acceptance?

To my knowledge the NBA teams do not have a revenue sharing system set up, or at least did not at the time of that case.

What makes the NFL different from the NBA which was forced to lower their age of acceptance?

The number of accepted and legal full-force collisions with 300-pound virtual blocks of granite. The NBA has 300-pounders, but their weight is distributed over a greater height. Also, the impacts are at far slower speeds, and with far less frequency. I'd say that protecting those who have not yet been though enough of those blunt-force traumas would be a legitimate concern. Clarett was playing against 180-pound HIGH SCHOOL linemen 18 months ago!
