what I notice the most is how long McKenna's legs are compared to Stenberg
Longer legs will give you more speed and power and make it easier to protect the puck but less explosive
shorter legs can give better acceleration, but not the top end speed, although, can make him harder to knock over (lower center of gravity).
Stenberg will need to expend a lot more energy to get from point A to point B compared to McKenna
McKenna also looks to have much longer arms and that is also a Huge advantage
they may be the same height, but, one has a clear advantage physically.
