I think some of you guys are overthinking this.
The coaches want four to five guys that can play press-man. We drafted two. We have signed several. I think Chido will get his chance to see if he can cut it, if not, he tries safety, if he can't cut that - he is traded for a late round pick to some team that needs a corner. The best four or five press corners and Brown, as the slot corner, will be our CBs in 2020.
I think the new staff likes Brown as the slot corner, which is why they gave him that large contract. The guy that is totally out of luck is Lewis. I am not going to pretend to know a lot about DB play, but the last staff preferred Brown to Lewis and based on the contract, this staff obviously does too.
