Spain National Team Flex Offense

Now I am sharing with you an ordinary flex offense played by Spain's National Team that they use sometimes with a very interesting tiny difference.

First we see the ordinary flex. 2 sets a cross
screen for 4 and pops to the top being down-
screened by 5. 1 can pass to 4 at the low
post or to 2 at the top of the key. If 1 passes
to 2 at the top then, 5 sets a ballscreen for 2.

But Sometime Spain plays like this.
2 sets a cross screen for 4, but 4 fakes and
slides up to the top of the key being scree-
ned by 5 in order to get a three point shoot.
