Carr himself has confirmed this via twitter.
The backend of the Ravens defense will need to play better next season but so far they’ve lost both Josh Wilson and Dawan Landry. Keeping Carr is a move move for the Ravens but they now have four cornerbacks that will be competing for two positions.
I would expect them to target a safetyin the coming days to make up for the loss of Landry. Speculative options could include: Bernard Pollard, Dashawn Goldson, and Donte Whitner.
