Have you never done or said anything in your lives that you've regretted?
Oh yes. In this thread even, I misspoke and managed to come across as defending DB's original tweet, when I was actually intending to ask why he was being so incompetent.
But he has not acted in the way I would expect a professional to act after a genuine fuck-up.
His first reaction should have been something like "I've taken that down now. I fully apologise for the offence and I can't believe I didn't see the implications for myself. Thank you very much to the all of you who've contacted me to alert me to the racist connotations of this image. More on this later".
Then he should have stopped tweeting while he got a clear-headed pal/paid P.R. professional to draft out a statement like the one he issued this afternoon.
For example, a really good move that a professional might have advised would be a promise to invite someone from a racial equality in sport charity to speak on the show, in order to redress the balance. Hmm, wonder if there are any of those specifically in football... 
The only thing that makes sense at this point is that he's trying to raise his celebrity profile through controversy.
