Jenkins comes to Philadelphia as one of the best starting safeties the Eagles have had recently (though that isn't necessarily saying much). As you can see, the 26-year old safety has a knack for making plays. His 2.5 sacks, 2 interceptions, and 2 forced fumbles in 2013 were more than any Eagles safety combined. In 71 career games played, Jenkins has recorded a total of 6 sacks, 3 defensive touchdowns, 38 passes defensed, 6 forced fumbles, 5 fumble recoveries, 276 tackles, and 88 assisted tackles.
