Derek Bodner of SB Nation's 76ers site Liberty Ballers notes how John Wall's presence has improved the Wizards and makes a comparison to Andrew Bynum's eventual return. Among the many interesting stats cited:
Once of the more telling stats was that without Wall, 14.5% of all three pointers made were unassisted. With Wall in the lineup, that's fallen down to 4.6%. Role players having to create more drastically decreases their efficiency.
It's a good read that I highly recommend checking out.
