It is undeniable that turnover differential has been key in Broncos games this year. As I'm sure everyone has heard over and over by now, the Broncos have won every game this year in witch they have won or been tied in the turnover battle. This is tough because the Broncos are the second worst team in the league in turnover differential, at -12.
One thing that I don't think gets enough attention is that while the Broncos have turned the ball over a lot this season (24 times), they have the FEWEST takeaways in the league, with 12.
Despite the defense's inability to cause turnovers, the onus has still been on the offense. The prevailing logic has been that as long as the offense (Read: Jay Cutler) is careful and limits turnovers, the Broncos will win games. Obviously, I'm all for the offense not turning the ball over, but even the most careful offenses still make mistakes.
The lack of takeaways is a big factor in why the Broncos rank only 10th in points per game, despite being 2nd in yards per game. If you look at the top 7 scoring teams in the league, you find that they have 26, 17, 21, 24, 23, 22, and 26 takeaways, compared to Denver's 12 (and the 17 belongs to the Saints who are 1st in yards per game). it's all about field position- which was Guru's big issue last season. A takeaway on the opponent's side of the field can turn into a field goal even if the offense stalls completely. Considering that the Broncos are only about 4 points per game behind the league lead, a few easy scores off turnovers would have made a big difference.
