That move at 1:34, aside from being extremely hard to pull off for players, doesn't utilize speed. The most effective way for fast players to use their skating to their advantage is to blow by on the wing, as Jake does.
As for switching it up, I agree with you there, and I'm sure he will as he gets more comfortable at the pro level.
To say he needs to "cut to the middle to use his speed" is an oxymoron, since players use their speed to get around defenders on the outside.
