We may have been "hot" compared to the Lambs back then, but that was then. This is now.
I suppose if you compare records against SF, then they logically have a shot a winning this game. But the whole "we beat X and X beat Y, so we can beat Y, too" doesn't work that well in the NFL. Wins are not commutative.
They do have Coach Fisher, who is a man to be reckoned with, but their talent level does not compare to ours.
It would not be out of line to predict our starters get more rest this week in the 4th quarter. Of course, you never know when a hot streak will end, but worrying about that will just end it sooner. Ride the wave.
