‘A published report mentioned the NFL Coaches Association sending a letter to the Bills regarding their blocked assistants. NFLCA executive director Larry Kennan said the letter is standard operating procedure; this year it also was sent to the Chicago Bears and Oakland Raiders, two other teams waiting for head coaches and not allowing assistants to interview elsewhere. The NFLCA’s primary goal, Kennan said, is to alter current rules regarding benefits for coaches. If a coach is fired, he receives his salary for the remainder of his contract but does not receive medical benefits or accrue years toward his pension.’
