If you want to argue the stats with the number guys, feel free. I don't create or store them. If I find interesting numbers I'll throw them out there..
Some much-needed context for the numbers you've thrown out there...
1) Since 2010, Romo's quarterback rating in the first 12 minutes of the fourth quarter is 81. In the final 3 minutes it drops to 44...So it's not a myth that he struggles mightily during crunch time and when it matters most.
Since 2010, Romo's passer rating in the final 3 minutes of the 4th quarter is 72.9. Manning's is 73.6 and Brady's is 70.5. These ratings are normal for this situation. The average for the NFL in the final 3 minutes of the 4th quarter is 71.2.
2) Since 2006 Tony leads the NFL in interceptions when leading in the 4th quarter by 7 points or less with 11. Clutch?
Since 2006, Romo has thrown 9 interceptions when leading in the 4th quarter by 7 points or less. This leads the NFL by one interception--one more than Tom Brady. He has also thrown 20 touchdown passes. 8 more than Brady. These QB have the most attempts in this situation:
Romo 149 of 226 2320 yd 10.3 ypa 20 td 9 int 112.7
PManning 136 of 214 1660 yd 7.8 ypa 10 td 2 int 99.0
Brees 177 of 253 1861 yd 7.4 ypa 9 td 5 int 94.7
Brady 151 of 240 1749 yd 7.3 ypa 12 td 8 int 87.7
Roethlisberger 124 of 214 1511 yd 7.1 ypa 7 td 4 int 82.9
The authors of the articles from which you pulled these two stats left out this information, for whatever reason.
