I'm not going to disagree that Brodie is a better defenseman than Barrie, but aren't both of them currently having pretty lame seasons? I'd imagine Brodie will pick it up fairly soon, but Barrie at his peak is a 50 pt defenseman and nowadays those are as rare as they come.
Brodie at his peak is a 50 point guy with solid defense and elite transition skills.
If we resign Backlund or Jankowski can play #2C or #3C next year I'd be open to trading Monahan though.
