I would trade a 4th only if he is going to resign. Cut Tutu or Nanee. It would be for security because we don't know how Gettis is going to be once he recovers. Also we have needed a true #2 for a long time now and he fits the bill perfectly.
Why? He hasn't had a chance to play? We've seen what Naanee can do, and obviously he should be cut.
