That's a huge reason for why the Cowboys ended up 8-8 and not 12 or 13 wins. Especially since their special teams sucked as well.
In 2016 Dallas had 20 takeaways and 15 giveaways for a +5 turnover differential which ranked them 9th in the league that year. Dallas Record 13-3
In 2019 Dallas had 17 takeaways and 18 giveaways for a -1 turnover differential which ranked them 18th in the league that year. Dallas Record 8-8
So what you are telling me is that had the Dallas defense caused 3 more takeaways (an average of .1875 takeaways/game) that Dallas would have won 5 more games that year? This in spite of the fact that the Dallas offense averaged 26.31 points/game in 2016 (which was slightly less than the 27.125 points/game average in 2019) while giving up 19.125 points/game (which was slightly less than the 20.06 points/game average in 2019)?
Hell I'm no expert but I can't see 3 takeaways in an entire season equating to 5 more wins.
