Gailey was 16-32 as Buffalo's head coach. Gailey was often maligned for having poor defenses, questionable game management and erratic quarterback play during his tenure. His handling of dynamic tailback C.J. Spiller also was a point of contention in Buffalo.
The Bills beat the New York Jets 28-9 in Sunday’s regular-season finale to cap back-to-back 6-10 seasons under Gailey. The Bills will be looking for their third head coach in the past five seasons.
