Just throwing this out there again with a pair of crucial Game 4s ahead:
Only nine NBA teams have rallied from 3-1 deficits — out of 219 attempts. The last time it happened was last year when Houston rallied to beat the Clippers.
Of the nine teams to rally from a 3-1 deficit, seven did so from a higher seeding than their opponent — in other words, having homecourt advantage and forcing/winning Game 7 at home.
