I'm way more worried about OT than I am CB or WR.
I am expecting the defense to rebound from last year, even without Darby and Gilmore, simply because we are going to let our strength (D-line) be our strength. That will trickle back to the LB's and DB's.
The offense should be as good as last year...if Tyrod isn't running for his life. OT is a big problem.
