I also wouldn't be surprised if they select 2 CB's in 2023 but I don't believe the #6 pick will be used on one.
There are a couple issues:
1) There are 5 "elite" prospects, not necessarily because they are elite but rather: QB'a are the big demand and end up in elite draft pick spots regardless whether they are worth it or not. So Stroud, Young, and Levis. Then there is Anderson and Carter, even if there is personality issues (might not "love" football/motivation, etc...).
2) After that, a lot of prospects with similar grades that result in not much trade down demand.
So I am arguing against a realistic possibility to trade down out of #6.
Which means, IMO, that #6 goes towards the best D-Lineman they evaluate (Murphy, Bresee or Wilson... maybe Carter if he falls to them?). As all those guys will be rated higher than the CB's, IMO.
So #18 should have a choice of half a dozen premium CB's, whoever falls and is available. That's one.
In the 2nd and 3rd round we have 3 picks, but I like the RB's, LB'ers, and Safeties more than the CB's that are available in that area. I think the Lions end up the same.
I think in mocks that I've run I found a project CB or two that were available with our 5th/ 6th round picks that I liked. As well as O-Lineman, Kickers, etc...
There's your second drafted CB. Another late round project. But I'm just guessing.
You know who I want as a second significant CB that we obtain this offseason? The best veteran that we can buy as a FA.
But that's just me...
