It absolutely is different from those things.
This isn't a scholarship, this is a job. This is the same as posting a job with a sign saying whites only.
The nfl could have achieved this through better ways like I suggested, easily.
Instead they wanted to be do this presumably to adjust perception after the Flores situation. It's still the wrong way to achieve a reasonable goal
No, it absolutely is not.
The NFL is effectively funding an internship for a year. At the end of the year they will presumably review the program, but my guess (if there are more details available I haven't seen them) is that teams can either hire those offensive coaching interns because they like them, or they can say "I don't have a job for you but I'll gladly give you a great reference to other teams", or they can shake their hand and walk away. Any which way, there will be 32 more experienced offensive coaches of colour who are now either working in football or with the experience of doing so.
This is an internship. I realise that a lot of the time and in a lot of industries interns are treated as minimum wage gofers who should just consider themselves lucky to be entrusted with coffee orders and dry cleaning and that somehow they'll parlay that into a career because they'll learn so much about their chosen industry simply by osmosis, but what the NFL is doing is how internships are actually supposed to work.
