In the NFL these days, with the rules, you are not winning without a top end QB.
Alex Smith is 9-0.
A much more accurate statement would be: In the NFL these days, you are not winning after massively overpaying to acquire a QB.
Current top-5 in NFL standings, and how they got their current starting QBs:
(9-0) Kansas City - Traded a 2nd and a conditional 3rd for Alex Smith (conditional has since turned to a 2nd).
(8-1) Seattle - Drafted Russel Wilson in the 3rd round
(7-1) Denver - Signed Peyton Manning as a free agent
(7-2) New England - Drafted Tom Brady in the 6th round
(6-2) New Orleans - Signed Drew Brees as a free agent
(6-2) San Francisco - Drafted Colin Kaepernick in the 2nd round
(3-5) Washington - Drafted Robert Griffen III 2nd overall, after trading three firsts and a second for the pick
Whoops, sorry. That last one clearly doesn't belong.
