I think it's more accurate to say that the Eagles disappeared at the right time. There's really no evidence of a suddenly improved Falcons offense - just a baffling absence of eagles defense. Prevent never works.
The amount of shock that was palpable as this drive was occurring was phenomenal. I don't think anyone believed it was actually happening. It was almost perfect, and I'd be willing to bet a lot of people still aren't sure it is real and they didn't just pass out and dream it.
What a dumb personal foul call, I didn't see exactly what it was, but I suspect excessive celebration or taunting? Would've been terrible if the kick missed.
