The names ahead of him: Brady, Brees, Peyton, Favre, Rothlisberger, Rivers, Marino, Rodgers, Elway, Eli, and Tarkenton. He could potentially end his career with 60K passing yards and over 400 TD's.
Only 7 QB's have done that and only 6 have done that and won a ring. He's getting in
If he plays 5 more years and averages 36 tds and 4000 yards he'll have 70k+ and 500+, which is right around Favre and Manning, with only Brady and Brees ahead of him. It's not completely outlandish that he could play until like 41, 42 and retire as the all time career leader in passing TDs and yards.
