THREE THINGS THAT NEED TO GO RIGHT ...
Control the clock. In beating Cleveland earlier this season, the Ravens held the ball for a season-high 37 minutes, 48 seconds. They are 3-0 this season when they control the clock for more than 35 minutes.
... AND THREE THINGS THAT COULD GO WRONG
Jamal Lewis breaks out against his former team. Since the Ravens held him to 56 yards rushing, Lewis has gained at least 79 yards in four straight games. He seems to be on the verge of recording his first 100-yard game of the season.
Browns offensive tackle Joe Thomas quiets Terrell Suggs. One of the most promising young offensive linemen in the NFL, Thomas can really solidify his reputation with a big game against Suggs, who has been the defense's top playmaker in the past two wins.
Turnovers dry up. The Ravens have returned an interception for a touchdown in the teams' past two meetings. But Cleveland quarterback Derek Anderson hasn't thrown an interception in 105 passes.
