Not that racism isn't a problem in football hiring (it obviously is), but I don't particularly like this argument whenever it's raised. Being good at a sport doesn't make you good at coaching and vice versa, and that goes triple when it's something hyperspecialized with tons of moving parts like the NFL, or the NBA to a lesser extent. Elite players don't often become good coaches or GMs, and often seem to become awful ones who only get the job because of their playing career (Isiah Thomas, for instance), and elite coaches for the most part seem to either come from coaching (Pop, The Dark Lord Belichick, Tomlin, Spo, Thibs), or from marginal pros who spent a lot more time watching than playing (Zen Master, Riley, Dungy, Cowher). I mean, when it comes to playing nobody has ever had more basketball expertise than MJ, and he's still been actively terrible at running the Hornets.
