As I said I would earlier, I ran a few more numbers on some players that I missed last night (mainly Winston, Bortles, Bradford, & Cutler). I ended cutting off the remaining players in the NFL at 20 games. Cutler started the fewest of the ones I did tonight (20GS). The reason I stopped at 20GS was b/c I was in the territory of where I was comparing QB's with 7-12 games started to QB's with 25-27 GS since 2015 and I felt any statistical significance would start to get lost due to the disparity in starts. In reality I shouldn't have included Dak either with only 11 GS but I thought it would be fun since he's such a hot topic currently.
Anyway, the red are the additional QB's I did tonight.
1. Tom Brady - 5.7; .783 2. Dak - 4.6; .909 3. Tyrod - 3.33; .560 4. Russel Wilson - 2.94; .630 5. Rodgers - 2.82; .556 6. Brees - 2.71; .462 7. Cam - 2.63; .731 8. Alex Smith - 2.62; .692 9. Stafford - 2.48; .519 10. Cousins - 2.45; .556 11. Dalton - 2.39; .542 12. Carr - 2.25; .593 13. Palmer - 1.89; .615 14. Eli - 1.83; .519 15. Big Ben - 1.8; .619 16. Rivers - 1.73; .333 17. Mariota - 1.71; .375 18. Tannehill - 1.64; .481 19. M. Ryan - 1.62; .556
20. Winston - 1.59; .444
21. Bortles - 1.49; .259 22. Luck - 1.46; .412 23. Fitz - 1.39; .480
24. Bradford - 1.35; .500 25. Flacco - 1.15; .429
26. Cutler - 1.13; .350
Of the 4 additional QB's I did tonight, only Bradford was really any sort of outlier. His Total TD/Total Turnover Ratio is pretty low, yet he manages to come in at exactly a .500 winning % (which as we can see is a substantially better winning % than the QB's he surrounded by).
I think a partial explanation for this outlier with Bradford is that in 3 of his first 4 wins this season (he has 5 wins as a starter this season) the Vikings managed to win despite the offense scoring less than 25 points in each of those wins. Because his TD to turnover ratio is low, meaning that he basically turns the ball over as frequently as he's involved in a TD, Bradford is an example of a QB who better have a really good defense if they're going to consistently win.
I'll update this list at the end of the year.
