Biggest question marks: Jared Gaither and Ed Reed. Gaither missed almost all of the offseason workouts because of a foot injury and sat out most of camp with a small tear in his back (this came after a dramatic weight loss). It's become difficult for the Ravens to think they can depend on him for the start of the regular season. Meanwhile, it was assumed that Reed would start the season on PUP. But Reed's progress has increased hope that he will be ready for the Sept. 13 season opener. Ultimately, it'll be Reed's decision.
