To elevate talent at essential positions will compensate for the lack of talent at others. Dallas has some Oline deficiencies, but they’re not voids. QBs don’t do it all by themselves, but they sure can make up for a lot.
Where did KC get Mahomes? Where did Buffalo get Allen? Where did GB get Rodgers? You get your QB from the top of the draft, as most everyone else has. Dallas misses on all the picks they don’t take.
Josh Allen was drafted 7th in the 2018 draft; Buffalo traded up from #12 (with TB) to select him; Dallas drafted #19 that season (LVE)
Patrick Mahomes was drafted 10th in the 2017 draft; KC traded up from #27 (with Buffalo) to select him; Dallas drafted #28 that season (Taco Charlton)
Aaron Rodgers was drafted 24th in the 2005 draft; Dallas drafted #11 that season (DeMarcus Ware)
So teams trade up when they see a QB they want and in the above 3 cases, 2 of the 3 teams traded up and as a result all 3 teams got QB's that took them to a Championship game or the Super Bowl.
Looking back at the Super Bowl winning QB's since the year 2000, here is a breakdown of what round the winning QB was drafted in (repeat winners such as Tom Brady count multiple times in the respective round selected):
1st round drafted: 11 (Dilfer, Roethlisberger, P. Manning, E. Manning, Rodgers, Flacco, Mahomes, Stafford)
2nd round drafted: 1 (Brees)
3rd round drafted: 2 (Wilson, Foles)
6th round drafted: 7 (Brady)
9th round drafted: 1 (Johnson)
So, of the last 22 Super Bowl winning QB's, 11 times (50%) have been by 1st round drafted QB's and 14 times (64%) by QB's selected in the first 3 rounds(Brady of course being the outlier with 7 victories as a 6th round draft pick).
While of course the likes of Brady and Johnson show it can be done, the fact of the matter is the odds of winning a Super Bowl with a QB not selected early dramatically lessens.
