The Ravens and Cowboys each are division leaders. Similarities end there.
Dallas is the NFL's hottest team, not having lost since the opener. It has that dynamic offense led by the league's best line and sensational rookies Ezekiel Elliott and Dak Prescott. Home-field advantage in the NFC is there for the taking.
Baltimore's only reason for being on top in the AFC North is how poorly the other division members have performed. The Ravens are too streaky, winning three, losing four, then winning two.
