Exploring How the Saints Could Trade Up for Cam Ward

You also don't see teams without a good QB on that list.
Sure. But the point of that list was to demonstrate that betting the house on a rookie QB normally (even overwhelmingly) does not lead to SBs. Because that's what this thread is about, how the Saints could trade to get Cam Ward, right?

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.
Sure they did... with a QB who was the 262th pick in the 2022 draft and made Trey Lance expendable, and a number of very good players around him.

And again, I am not saying teams don't need good QBs... what I am saying is, teams don't need to spend a boatload of picks to take a QB within the first 10 picks of the draft, because in today's NFL, it rarely leads to SB wins.
