I'm hoping that they can somehow come up with Brock Bowers, but Dejean would be a nice consolation prize.
At the same time, if the team plans to run a whole lot of zone coverages next year, I could see an argument on passing on him. This would not be because he'd be a poor fit but because qualify zone CBs can be had later. Especially, in this deep CB draft class.
I could see the argument on not using the #19 selection on a CB they didn't believe had the potential to be a shutdown type CB. Someone you can place on an island and allow DCs to funnel other coverage personnel elsewhere.
