Defenses are usually ahead of offenses early in the season, and that's to be expected. But watching the Ravens' offense perform Monday was downright frustrating. The Ravens were without starting offensive center Matt Birk and right guard Marshal Yanda, and their absences were partly to blame. But this offense has no consistency in the passing or running games. The good news is the season is still young and the Ravens have plenty of time to improve, but you'd figure there would be more cohesiveness in a unit that has some key starters returning. There were times when the backup quarterbacks couldn't handle exchanges or tripped over their feet while dropping back. At one point, it was so ugly that offensive coordinator Cam Cameron said, "Some of you guys are thinking about tomorrow, but there might not be a tomorrow for some of you."
