Carter is 3 now, and ready to take the ice on skates.
In a new MassMutual commercial, the Tampa Bay Lightning captain and defenseman Victor Hedman are watching a hockey practice when Stamkos asks Hedman why his son hasn't started playing yet.
"He's only six months old," Hedman said, holding his son in a sling.
Stamkos responded saying, "I guess hockey is not really his thing," just seconds before 3-year-old Carter slams a grown player into the boards and waltzes away with the puck.
