Might have been covered already but you're right in that he called the Campbell trade. Friedge also credited him but obviously refused to say the name as its a burner account, but speculation is that he has ties to a player in the org.He posts strictly regarding the Leafs. There's 2 things I can see happening, and I hope I'm wrong but I have a weird feeling if this is true, it's going to be for either, Subban or Doughty.
Supposedly his Twitter account showed ties to the Dallas area so people are guessing Campbell is his source (drafted there).
