He might have a blessing now, but if the Dolphins don't win, that blessing could evaporate in the time it took me to type this post. Parcells doesn't fuck around, and if he thinks Sparano can't handle a head coaching job, he'll cut the guy loose and take over.
I'd love to be a fly on the wall if that happens.
You are assuming Parcell wants to coach again.
Also, if the Dolphins don't win, then the only person to pin the blame on is Parcells. He should be escape the blame, since he hand picked everyone. By that he should also go.
