Few things here:
First, playing the injury game is a bad idea. If Akers goes down, Henderson is injury prone and we have nothing behind him. Kupp has only played two out of six possible playoff games. Both Kiser and Howard are coming off injury. You can go round and round with the injury game - so not worth using it in this context because everything becomes a need.
Second, with Ramsey, Williams and Hill all healthy last year, Rodgers torched us in the playoffs - so if having a great trio of CBs can't prevent that from happening, why keep investing in the position?
Third, if you want to say the above was just one bad game, that's fine - the real answer there is that it happened because we got no pressure on Rodgers. While AD was hurt, were back to the circular injury argument - but I'd point out that the Bucs had much more success against Rodgers and their secondary wasn't half as good as ours.
I think both OL and CB are needs, but we pay Ramsey to elevate the CB room. And I think it's possible we re-sign Williams anyways
