Daniel Edward Reeves (born January 19, 1944) is a former American football running back and coach in the National Football League (NFL). He participated in a combined nine Super Bowls as player and coach, the second-most in league history behind Bill Belichick's ten. Reeves played in two Super Bowls (V, VI), was an assistant coach in three more (X, XII, XIII), and was head coach in four: XXI, XXII, and XXIV with the Denver Broncos, and XXXIII with the Atlanta Falcons. Reeves is tied with Jeff Fisher for the NFL record of most regular-season losses as a head coach, with 165, though both coaches have an overall winning record. Wikipedia
