what is decon on nfl uniforms?
 Deacon was as innovative, quick thinking and flamboyant out of uniform as he was fabulous on the field. Even before he became a great star, he was determined to attract his share of attention. One of his first acts as a Rams rookie was to put aside his given name David and substitute a nickname Deacon. He was named the NFL's Defensive Player of the Year by his fellow players in back-to-back seasons in 1967 and 1968.
