I think Rasul's had a better year than Jaire, injury aside.
Trading Rasul opened a path for Valentine and/or Stokes (who is in trouble IMO) to get snaps as well.

I absolutely think they will draft a CB...preferably one who can play both outside and in the slot.
I think Jaire will be focused after the suspension and next year, I think Valentine will improve. Stokes injuries are concerning, especially for a player who relies so much on his athleticism and speed to cover. He might never be the same.

I love Rasul but he wasn't a fit in their long term plans.
