He's still just 20 years old, so I don't want to rag on him too much as sometimes I forget how young a lot of our core still is. But the back-checking irritates me to no end. I'm a firm believer in working just as hard without the puck as you do with the puck, and for the most part MacKinnon does. But on the back-check a lot of times he's caught flat footed and stops skating.
Tonight for instance in the 2nd period, I believe we were on the PP but he was actually ahead of the Kings player, and then he just stopped moving his feet and let his man beat him up the ice. Thankfully, Beauchemin blocked the shot from the other Kings player as it became a mini two-on-one. But things like that are preventable and all it takes is the most simple, basic thing a hockey player can do. Just move your feet.
