NFL X Sun -Denver -2 1/2 If there was ever a preseason game that was 'must win', this is it for Denver. This is the Broncos first home game under the new regime. They are 0-2 so far, and an 0-3 start would be devastating especially against Cutler. I doubt if Chicago has the same urgency in this situation as Denver will. I suspect the Denver starters to play well into the 4th quarter with Orton possibly going the whole game. Simms (backup qb) is out for 2 weeks and with Denver playing their final exibition 4 days later, the 2nd stringers will see plenty of action on Friday.
