Kessel, who ranks 10th in NHL scoring with 18 goals and 41 points in 40 games, has one goal in his past nine games and three in his past 12.
"Obviously we haven't been winning and that's what happens; they're going to come after you," Kessel said. "It's never fun, but it's part of the business."
Former Maple Leafs coach Ron Wilson suggested Tuesday during a radio interview that the core group of players on the Maple Leafs, which includes Kessel, may be uncoachable. Kessel was asked about his former coach’s statement and said, "I don't really care, to be honest with you. I didn't see it, so it doesn't really faze me."
