MacKinnon entered Tuesday with three more goals than anyone else in the NHL, and with 12 points, was tied for the playoff scoring lead with Tampa Bay Lightning forward Nikita Kucherov (three goals, nine assists).
"I don't think it's just a hot streak," Ferraro said. "I do think he can continue to do what he's doing. He's not going to get four points every night, but I don't see why all of a sudden he's going to run dry. … It looks to me like when he gets the puck, he's going downhill. Like, the speed and the power, it jumps out of your TV at you."
MacKinnon has a strong supporting cast.
Colorado's top line of MacKinnon with forwards Gabriel Landeskog and Mikko Rantanen is one of the best in the League, rivaled by perhaps Boston's top line of Brad Marchand, Patrice Bergeron and David Pastrnak in the way the players complement each other.
Led by Cale Makar, Colorado's defense makes the most of the forwards' talent.
"MacKinnon can be the fastest guy in the world, but if he's starting from a standstill all the time, he's not the fastest guy," Ferraro said. "Those guys get them the puck at the right time, at the right moment, in stride, and that allows them to play that much quicker.
"Like, they're an impressive, impressive team."
Ferraro compared MacKinnon's determination to improve to that of a young Sidney Crosby, the Pittsburgh Penguins captain. Crosby, the No. 1 pick in the 2005 NHL Draft, and MacKinnon, the No. 1 pick in the 2013 NHL Draft, are from Nova Scotia and train together.
Though Ferraro said he is mesmerized by the skating of MacKinnon and Edmonton Oilers center Connor McDavid, it's for different reasons.
"In Connor's skating, there's just an elegance to it," Ferraro said. "It's a beautiful, beautiful stride. And with MacKinnon, to me, it's just so powerful. It's like he just chews the ice up."
MacKinnon is a force all his own.
"He can beat you different ways that other people just can't," Ferraro said. "Clearly, he can skate around you, and if he wants, it looks like he can go right over top of you. And there's not many players that are even built that way.
"And you look at the hands that he has. Honestly, I find it mesmerizing when he skates up the ice at whatever speed he's going, and his hands are moving so fast. Like, it's remarkable how fast he stickhandles the puck, and that's what he does, the main thing he does that other people can't do."
