DT is by far the biggest need on this team. They have 3 on the roster now: Ed, Jones, Ankou. If Ankou has to play meaningful snaps in season they are done. That means they need atleast 2 DT. They need another Edge too.
Now look at Josh's weapons. Most likely targets breakdown:1. Diggs, 2. Kincaid 3. Samuel, 4. Shakir, 5. Cook, 6. Knox. Rookie WR comes in the ceiling is number 4 at best in target share.
Do I want a receiver? Yes, if that's your BPA, you take him. However the front four has serious needs. If Murphy, Darius Robinson, or Newton is there you take them.
