I believe the comp picks system is dumb because it suggests owners aren't picking black GM's (or Black coaches) based on skin color. I don't believe thats the case. Tony Dungy and Mike Tomlin are some of the best coaches the NFL ever had, I don't believe any owner (well most, I'm sure there's a redneck or two still in there somewhere) would exclude any none white candidate from the job based on skin tone.
The problem is supply. I often see "The players are 70% Black". What's that got to do with anything? Players rarely go on to become top coaches or GMs. Or even bad ones. Most players are good at playing football but couldn't run a McDonalds franchise, no matter their skin colour. Those that are smart are often millionaires many times over by 30 but with no coaching experience. How many are going to start out as a quality control coach on 60k a year? Even those that don't stick around the league often make enough money to do something like intense, even a poor player that hangs around the league long enough can earn enough money to get into property or something else where they don't need to work 70 hour weeks.
Mike Tomlin is a great HC because he spent years learning to be a great HC. He wasn't a pro player. He came up through college and position coach ranks.
Tony Dungy was a washout in the NFL who did the same. Went and coached college ball and worked his way up.
So the percentage of players who are black or white has nothing to do with the supply pool for coaching and GM positions.
Brad Holmes, the new Lions GM worked for the Rams for 20 years starting as a scouting assistant. You want more minority coaches and GM's? You need more supply. You need more of them in the grass roots of coaching and FO jobs. More scouts, more assistants, more college position coaches etc. The NFL should start a placement or training scheme for all NFL players that wash out the league before they are vested if they have the college degrees to qualify.
Offering comp picks is not the answer.
