Talk about a comeback/collapse of epic proportions

This is one of the best 2 minute 10 second drills of recent memory. The Colts came back to beat the Texans because of 21 points in the span of 2:10. Matt Schaub's back-up, Sage Rosenfels, aided the Colts by fumbling twice and throwing a pick. I would be easy for me to slam the back-up here but they had the lead with about two minutes left. Why is the back-up QB still scrambling? You have to blame the playcalling. Just pound the ball and don't let the back-up determine the game.
