Laboral Kutxa Baskonia Transition Offense

In this post we're checking a nice Transition Offense by Laboral Kutxa Baskonia that they usually play to isolate 4 at the low post.

From the set shown in this picture, 1 hits 2
and cuts to the left side wing being cross 
screened by 4.

2 dribbles to the top, hits 1 and cuts to the rim
being backscreened by 4. Then moves to the
right corner.

Finally, 4 sets a ballscreen for 1 and rolls to the
rim. Simultaneously 5 sets a downscreen for 3.
1 comes hard off the screen hits 3 and 3 hits 4
at the low post.
