Jeremy Butler

Ryan Mallett led the Baltimore Ravens to an upset victory over the rival Pittsburgh Steelers eight months ago. He has a 99.5 quarterback rating and a 74 percent completion rate through two preseason games.

Despite that success, Mallett could lose the backup quarterback job to surprisingly electric journeyman Josh Johnson, according to coach John Harbaugh.

In Baltimore's 19-18 preseason win at the Indianapolis Colts, Johnson led the team in passing and rushing, showing great touch on his throws and the ability to scramble for yards. His best moment came when he directed a near flawless two-minute drill before halftime, driving the Ravens 79 yards with poise and hitting Jeremy Butler for a 12-yard touchdown.

"[Johnson] is making a case to make this team," Harbaugh said after the game. "There is a competition for that spot. It's been on-going through training camp."

The story said it's been long assumed that Mallett is the primary backup to Joe Flacco. He took all the first-team reps in the spring when Flacco was sidelined while recovering from knee surgery, and he started both preseason games.
