In his promotion to referee, NFL officiating director Mike Pereira said of Cheffers, "Carl has been extremely successful on the field as a side judge. He is very knowledgeable of the rules, a good rules guy. Strong presence. He was part of Larry Nemmers' crew and he was clearly a crew leader. When we first saw Carl, we saw referee experience from him even though he had refereed basically at the small-college level."
