He is insurance/depth (for 2019) and I don't see him as being a starter by any means in 2020. But could he be the CB4 in 2020 with Long starting and NRC the nickel? Definitely could.

There is a $2M cap hit if they trade or release him this year so that's why I would say he is not tradable (unless someone comes calling with a 3rd round pick or something which just isn't happening).
