I know that some people hate the idea of drafting another first or second round CB next year, but really... don't be surprised.
It won't be because Grier/Flores have an unhealthy fascination with CBs either. Most CBs don't play well after 30, and both Jones and Hoard are 28 (as is Coleman). Two, maybe three years left before they lose a step and fall way off, and CB is one of the prime positions in the NFL. If you have bad CBs, you lose... period.
Iggy is still 21 and he's the future. Needham is 24 and might stick around awhile, but after that... not much.
We'll need more... we'll ALWAYS need more, and I think it's odd that so many seem to understand that RBs are largely disposable without realizing that CBs are almost as limited... while you need more of them and factoring in their greater importance.
Flores/Grier know all of this, and you can see it by the way both Hoard and Jones' contracts were structured... paying them less at the end of the contracts, as their speed will be waning.
