PFF - have y'all seen this

I understand your argument is likely based on the article you linked that specifically stated the last 5 seasons, but posting those conversion rates while leaving out Carr's first four seasons where he started every game except for 2 (one in 2016 and one in 2017) and they excelled in the redzone (when they actually did get there) seems a bit cherrypicked.
I was bored and had a little time before dinner, so I just looked up a few thing. Raw stats and high level metrics but here they are:

Brees (18-20)
--------------
146/209 - 69.9%
59TDs/1INT
Passer Rating: 116.31
TD Rate: 28.2%
Yards: 924

Winston (18-22)
------------------------
92/153 - 60.1%
49TD/3INT
Passer Rating: 104.2
TD Rate: 32%
758 yards

Dalton (18-22)
-----------------------
140/238 - 58.8%
53TD/8INT
Passer Rating:93.28
TD Rate:22.2%
Yards: 948

Carr
-------------------------
(14-17)
117/231 - 50.6%
66TDs/5INTs
Passer Rating:88.91
TD Rate: 28.6%
779 yards

(18-22)
191/359 - 53.2%
73TDs/10INTs
Passer Rating:88.07
TD Rate: 20.3%
1178 yards

Using that same criteria, one QB is 1st in passer rating, 1st in completion percentage, 7th in TD percentage, and has the lowest interception percentage. He doesn’t have the passing plus rushing TD totals because he hasn’t played in two years, but he still managed to finish 19th overall in that category. Everyone knows who it is—Drew Brees.
BOOM!!!
