I would guess that any who got picked for NFL did VERY well, and the ones who did not get picked did poorly.
If I was an employer, I would look at them and decide (probably accurately) that they learned nothing but football.
You would think that a person who played NFL football for even a short time would accrue considerable benefit. Not so sure. Ten years after playing, those ex athletes are often broke and are saddled with life long debilitating injuries. Some of course did very well. Would love to see an objective study how eighteen year old African American males who are recruited to play in Division 1 university sport programs fare in the long run compared to their peers who are not recruited.
