Nah. Rackers had just pissed out rocks. He wasn't at full strength and would have most likely missed the FG, thus giving the Redskins a short field. This is exactly what happened to the Redskins when their kicker missed his second try. The Texans had a short field and ended the game. And McNabb torched the secondary because there was no pass rush until the second half (mainly the fourth quarter). The Texans D had been doing well against the Redskins offense the previous few drives, so Kubiak had faith. It worked.
