2016 is turning out to be a pretty bad year for my childhood heroes.
Hard for people today to appreciate just how big a figure Muhammad Ali was in the 60s and 70s.
He truly was the greatest. And he always will be to me.
This amazing tribute by Mos Def and calligraffitist Niels Shoe Meulman was made by Ogilvy Paris about 4 years ago.
The words are Ali's. They will echo down the ages.
