During an injury-riddled season last year, the Ravens' secondary was uncharacteristically vulnerable because of constant personnel changes at cornerback.
Largely because of that problem, the Ravens' otherwise strong and eighth-ranked defense finished 23rd in the NFL in pass defense, as they allowed 248.7 passing yards per game.
The Ravens didn't exactly overhaul the secondary this offseason, but did sign former Houston Texans and Kansas City Chiefs defensive back Kendrick Lewis to a three-year, $5.4 million contract as their new starting free safety. And they're banking on healthy seasons from starting cornerbacks Jimmy Smith and Lardarius Webb this year after they battled a Lisfranc foot sprain and a back injury, respectively, last season.
