襪飯, I would wait after the season starts to consider the trade. If he trades away Javon Walker now, his no.1 receiver will be either Lee Evans or Deion Branch. Both of them at this stage, are a little weak for the No.1 wide receiver role comparing to other teams.

The best case for 襪飯 is that Dunn holds onto his starting role as season all season long. Bottom line is he is the starter for now and there is no short term emergency to worry about.

Just my 2 cents.
