The Players:
Jimmy Smith, Lardarius Webb, Kyle Arrington, Tray Walker, Asa Jackson, Cassius Vaughn, Chris Greenwood, Tramain Jacobs, Quinton Pointer, Rashaan Melvin
Guaranteed:
Jimmy Smith
Jimmy is the best corner on the team and he just signed a lucrative extension that keeps him in Baltimore for the rest of the decade. He's guaranteed to make the roster.
Lardarius Webb
He's guaranteed to be on the team; this year. However, if he isn't healthy or if he doesn't return to form, the same can't be said next year when the Ravens can save $3.5 million by cutting him.
Kyle Arrington
The Ravens made it a point to snag this guy after the Patriots released him. He's not getting cut.
Tray Walker
Walker is a fourth round pick, so his spot is guaranteed. Especially seeing as the Ravens have a high opinion of him. That being said, I don't see Walker making the active list very often, but instead I see him sitting behind Webb, Jimmy, and Arrington to develop.
Probable:
Rashaan Melvin
Melvin has five good games under his belt from last year. He's a good development project and a back-up.
In Competion:
Asa Jackson and Cassius Vaughn are fighting for the sixth and last corner spot. I see this battle coming down to who is better at returning kicks and whether Asa is able to stay healthy. Whoever loses is gone.
Practice Squad:
Chris Greenwood, Tramain Jacobs, Quinton Pointer
These three are fighting for one or two practice squad spots. If anyone looks particularly great, one of these guys could push in competition.
