lets assume it is the PG:
PG: A - A -A
SG: B-C
SF: D -E
PF: F -G
C: H- I
And J on the bench will come in for a in the blowout. You could salso line him at the reserve of A, which gives a little higher risk that he comes in early, but will give the right result in case of injurys.
And there is also an risk that the blowout start some minutes earlier.
