The play begins with a line and gets the 5 and 4 to the corners. This 'stresses' X5 or allows open corner shots for the bigs.
The ball swings toward the top and screening action creates multiple options:
1) The 3 has a curl to the middle.
2) 4 might be open over the top.
3) 2 is 'the alternative' (via screen-the-screeners action - STS) to "America's Play" where 5 screens 3 for a corner shot.
