McDaniels challenged both those plays in the first half because he understands his homefield advantage. There was small chance the challenge of the fumlbe wouldn't be overuled, but he knew that as long as he kept the game close, he'd have a great chance in the end. The second half at mile high is very tough on defenses, and historically Denver has always scored more points in the later quarters. McDaniels also knows the higher time of possesion, the greater his home field advantage. He wanted his offense on the field as long as possible, and the early challenge on the 3 yard reception was for exactly that reason. The people I was watching the game with thought they were very stupid challenges. I kept my mouth shut, but I didn't think either call challenge was "stupid". I probably wouldn't have challenged the fumble, but I understand why he did it, and I agree with the decision to challenge the 3 yard reception. If you can keep your oponent in long down and distance situations, you'll win the time of possession battle. McDaniel's challenges were right in-line with his game plan, NE's Time of Possession was 28:22, and Denver won the game.
