One of the final portions of the Ravens’ joint practice with the Los Angeles Rams on Monday pitted their offense against the Rams defense in a two-minute situation. In three possessions, the offense emerged with zero points. The opening series, with quarterback Joe Flacco under center, was the most promising, as the unit drove to Los Angeles’ 40-yard line. But on third down, Flacco overthrew a deep pass along the right sideline to wide receiver Chris Moore, and kicker Justin Tucker’s field-goal attempt from 58 yards missed wide left. The Ravens’ ensuing drives, led by rookie Lamar Jackson and Robert Griffin III, did not get close to crossing midfield.
