"He's playing at a very high, high level right now and the team is playing well around him," Oilers coach Todd McLellan said.
Kunitz said there are many similarities between two-time Hart Trophy winner Sidney Crosby, his former teammate with the Pittsburgh Penguins, and McDavid.
"They don't have a fear button," Kunitz said. "They don't go wide on guys, they take it right through the middle. They enjoy the contact almost. You just want to get them the puck as quick as you can. You just give it to him with time to skate with it.
"They want to be the best every single time they step on the ice. They're driven by more than just wins and points. They're driven by how they can change the game, or maybe it's the individual status of trying to be the best that's ever played the game."
Oilers forward Leon Draisaitl had a goal and two assists Monday playing on a line with McDavid and Mike Cammalleri, and said McDavid earns everything he gets.
"When you are as good as he is, there is no such thing as luck," Draisaitl said. "You create your own bounces. He just has that ability to take a game over. There are very, very few players in this world who can do something like that.
"It seems like he is from another planet. It is not fair, really. He works hard and it is not just a given talent. He works on the stuff he wants to work on and that is what makes him so good."
McDavid has eight points (six goals, two assists) in the past three games and 13 points (six goals, seven assists) in the past seven, when Edmonton is 5-1-1.
