It's possible. But a few things to consider.
1) The refs sucked today. The flagrant foul on Jermaine that was barely even a regular foul, the no-call flagrant on Jones, and the second T on Pierce radically changed the game. In all three instances the C's were making a run and threatening to close the lead to a few points and the refs blew it. If the C's make a big enough stink about it today and tomorrow, the refs will have to stop that crap.
2) Wade played out of his mind. Wade is a fairly good shooter, but he won't shoot 70% on those shots any other game this series.
3) Rondo missed the entire second quarter, Pierce missed most of the 4th, and there was no Shaq. Hopefully none of those things will ever happen again.
4) Jones likely won't do that again.
Granted, LeBron and Bosh will likely play better in other games; however, they likely won't shoot a high enough percentage to outweigh what Jones and Wade did today.
