It was the positive net-balance of Rockets' defense and offense that won them the game. I subscribe to defense win championship battle-cry, but it is not ALL about lockdown D.Rockets turn Staples into death watch morgue... in 4Q and all without "runner up MVP." Clips played laughably bad in 4th but Rockets defense was utterly tenacious. Yes, playoffs and especially in crunch time is all about lockdown D! Now game 7 in H-Town.
Don't forget about Josh Smith and Brewer's offensive contributions during that crucial stretch. Those were actually as equally important.
