If you've been working on your Eurostep in your free time, you've presumably been doing two things wrong. That applies even if you've been faking defenders out of their shoes en route to easy sets of two points at the basket.
But don't worry; I don't blame you. You couldn't be expected to succeed without the aid of this video.
First, you should be listening to James Harden. Not only is he one of the true masters of the move during real-time NBA action, but he's an incredible instructor who should have chosen a more pedagogical career.
How can you go wrong with his flawless examples of what to do and what not to do? Do you know how hard it was for Harden to fall down like that, simply because he needed to give a poor example?
The other key is the beard—obviously.
Don't view it as a distraction, even though it's easy to get lost in the follicular forest as Harden runs a comb through his man-beard. It's not a distraction; it's motivation.
I'm sorry, but if you don't have a beard like this, you're not going to be able to Eurostep like the Houston Rockets 2-guard.
You want to be able to fake defenders out of their shoes, don't you? Then you have to get that footwork down while distracting the man guarding you with the awesomeness that covers up the not-so-awesomeness of your cheeks and chin.
Now get out there and practice, assuming you haven't been blinded by Harden's facial hair.
