Re: Faster low rated player
The video needs to go back farther so I can see how Kucherov starts skating. His energy is also going to be a factor. When you're outside of a replay, you should see that meter. From what I can gather with this clip though, Kucherov is slowed down by turning as well as the slight speed penalty when carrying the puck. He starts out facing to the right, then switches directions. This will slow him down. Then, he skates to the left before going in to a straight line. With Dickinson sprinting in a straight line, he's able to catch him. This is intended.
This is why I say nobody has proven that lower speed players are legitimately beating higher speed players. They always show the carrier turning, deking, being flatfooted, etc. If 2 players are side by side with the same energy skating the length of the ice and the slower player is beating them, that could be an issue. Your video is showing what is intended to happen based on the current mechanics of the game.
