NFL slow with Hiring more Black Coaches

now granted there are 6 Black Head Football coaches in the NFL,but with the recent opening of 10 jobs thus far quite a few coaches with no previous head coaching jobs have gotten the gigs&what makes it so bad is that 3 of the top football coaches this year are Black.Tony dungy,Lovie smith(who Won Coach of the year with the chicago Bears)&Marvin Lewis all were top coaches this year.i hope the NFL don't go backwards.I remember just 18 years ago when Art shell got hired with the Oakland Radiers,but hasn't had a gig since which is a real mystery. no matter what some folks think there is stll quite a few NFl higher ups who don't feel a Black Man Can Lead a team.the NFL says the National football League,but sometimes like in other areas of up grade in a Job I wonder if it means Negros Forget Leadership??
