I'd trade Diggs for Donald today, and I LOVE Diggs on this team. It would leave us thin at corner, but imagine having guys like Micah, Lawrence, and Williams coming off the edge, Hankins or Mazi demanding double teams, and Donald creating chaos across the interior line.
Our safeties and linebackers are good enough and fast enough to swarm the ball on short passes. Anything intermediate or long is out of the question because the pocket will collapse 80% of the time. Is it necessary to have an all-pro corner with that kind of lineup?
Running up the middle would be impossible, and good luck getting to the edge with that speed on the field.
Diggs is due a big contract, and I'd imagine Donald would warrant about the same, if not a little more. Well worth the additional investment for what he brings to the table.
