Why consider the 1-4 low set for BLOBs? It provides versatility and distorts any zone alignment because both the posts and perimeter are immediate threats.
Here are just a few of the simple possibilities...and you can create far more options.
Post entry into a pick-and-roll handoff.
Double stagger away...the Celtics have run a version of this.
High post entry with screen on the big...if you're not afraid of getting your 1 clobbered.
Elevator screen. Usually we see this out of a box.
With a little imagination, you can run some of these as 'sets' in the half court, if the players aren't mentally too taxed.
