Again, I'm not trying to say NO SIR THEY CAN NEVER BEAT THE STEELERS because quite frankly, any team can beat any other team on any day.
However, with both teams at full strength, every indicator is that the Eagles can't handle the Steelers running game, and their passing game will be stunted by the Steelers' blitz (which it did pretty nicely in the first game) when the Eagles can't run the ball against their stout front seven.
