Because they would openly speculate if there wasn’t some smoke to the story. Boomer in particular makes it seem pretty likely.I don't see either of those guys saying Tkachuk's on the move / about to be traded. Just "if he's traded, this is why..." stuff.
Keep in mind they are still mouthpieces to the org (well, not in boomer’s case anymore). If they think he’s on the outs, he’s probably on the outs. Leslie was suggesting Gaudreau was probably gone, and look how that turned out.
