With PJ banged up, Bell banged up, P-Rob banged up, CGJ a rookie, and Apple getting burnt, sliced, flagged, fried, and diced...
We need DB help however we can get it.
Whatever Jenkins "is" at this time, I think he's WAY WAY WAY better than any DB any of us even even dared dream we'd be able to pick up two weeks before the playoffs.
In Dennis Allen's scheme, we often like to have a lot of DBs on the field and there isn't really all that much difference between strong safety and slot corner.
And regardless how we line them up or who we start where and when... losing a starting corner in the playoffs could mean an early exit. Having an Eli Apple or Janoris Jenkins to come off the bench could mean a championship.
