The analysts on the TSN show said it, it didn't get fabricated here. Kessel's problems with Skille and Johnson, or vice versa, have been around articles on hockey sites and elsewhere for a long time. Calling someone a liar here really increases your credibility.
Rumours here make it sound like it's a hassle between families, with Kessel's mom at the center of the controversy.
Whether the "family feud" causes a riff on the team is debateable, obviously it would be better for the other teams if it did.
