A weekly look at what the Baltimore Ravens must fix:

There used to be a time when quarterbacks feared throwing against the Ravens' safeties. That's a distant memory now.

When the Ravens line up Sunday against Indianapolis Colts quarterback Andrew Luck, Matt Elam and Darian Stewart will have bulls-eyes on their backs. The problem is Elam and Stewart are both strong safeties who excel playing close to the line of scrimmage and struggle when in coverage.

That has been apparent all season, and it was the team's major weakness again last Sunday. Stewart allowed four of the five passes thrown in his direction to get completed for 67 yards. His slow reaction time was the reason why Panthers wide receiver Kelvin Benjamin was so wide-open for Carolina's only touchdown of the game. Stewart was supposed to have the deep zone on that play, and he wasn't even close when Benjamin caught the ball in the end zone.

Elam didn't fare much better, failing to break up any of the three passes thrown at him. The former first-round pick gave up 61 yards passing. Injuries have forced Elam into a tough position of playing nickelback, which requires him to cover the slot receiver. While Elam played tighter coverage than earlier in the season, he didn't turn to make a play on the ball.

Only time will help the Ravens in pass coverage. When cornerback Lardarius Webb is back at full strength, the Ravens can use Webb or Asa Jackson at nickelback. There will also be another option at safety in two more games, when Will Hill comes off suspension. These aren't definite solutions, but they can become immediate upgrades.
