The Dallas defense was 14th in yards, 23rd in drive time, 29th in plays per drive, 25th in yards per drive, and 17th in points per drive and 20th in TO percentage. They put up decent totals because Dak and Zeke kept them off the field but they were not a good defense.
More importantly, Dak played one more game than TT and beat him in both totals, % stats, GWD, 4Q comebacks, everything. I don't think TT had a single stat better than Dak in 2016.
When a QB scores 2 more TD's, throws 2 less picks, throws for 600 more yards, has a NY/A of 7.28 compared to 6.79, and takes 11 less sacks at half the sack percentage, all while putting up 4 more GWD's, that makes the difference between good and great.
