Exploring How the Saints Could Trade Up for Cam Ward

You also don't see teams without a good QB on that list. Even Flacco and Foles who aren't elite had amazing runs to get to the Super Bowl with each winning Super Bowl MVP. You're simply not winning anything without a QB.

You're also not screwed if you trade up and fail. The 49ers gave up 3 first round picks and a 3rd to get Trey Lance. Completely whiffed and played in the Superbowl 2-3 years later.
What you and Systemshock are showing is that there isn't any significant statistical correlation between when a QB is drafted and a team winning the the Super Bowl. Top 10 drafted QB's don't have a statistically higher correlation than QB's not drafted in the top 10 and vice versa.

You have to have a good QB, but you're just as likely to find a good enough QB outside of the top 10 picks as you will find one inside the top 10 picks. If you have a top 10 pick, great. If you don't have a top 10 pick, you don't have to use up extra resources to get into the top 10 to draft a QB.

It's not truly a "top 10 or bust" situation like so many seem to think it is.
