Why Challenge?

I'll tell you why Andy Reid challenged the call....the Colts play so crisply and Manning gets them together so efficiently after a big play that AR had to go with his gut...no waiting for replay as the Colts meander down the field....nope they run down there, and force the issue...you wanna take a chance? Did he catch it or not? At a time when so many teams plod down the field, the Colts get other teams to waste challenges and timeouts by playing with a sense of urgency...
