Exploring How the Saints Could Trade Up for Cam Ward

You could do some research yourself... first search hit I got was an ESPN article from 2021, listing them all to that point in time (according to them).

Between 2000 and 2021, 1st round, top 1-10 picks:

Josh Rosen 10th overall - bust
Mitchell Trubisky 2nd overall - bust
Robert Griffin III 2nd overall (who wasn't a bust really, he got hurt, but still...)
Sam Darnold 3rd overall - bust for the Jets/Panthers/9ers (we'll see with the Seahawks)
Jared Goff 1st overall - Rams/Lions teams so good, they won a lot of games even with him at QB
Trey Lance 3rd overall - bust for the 9ers, on his 3rd team.
Carson Wentz 2nd overall - bust
Blaine Gabbert 10th overall - bust
Mark Sanchez 5th overall - el busto supremo
Michael Vick 1st overall - was doing well, until...

1st round:

Tim Tebow
Kyle Boller
DeShaun Watson
Paxton Lynch
Johnny Manziel
Teddy Bridgewater
Paxton Lynch
Josh Freeman
Brady Quinn
Jay Cutler
Jason Campbell
J.P. Lossman

Before 2000, not pretty either... you got Ryan Leaf, Jeff George, Steve Fuller... Steve Bartkowski...

The only 4 successful QBs that have been part of a draft day trade for a pick in the draft are Josh Allen ( 7th overall, no SB yet), Jordan Love (26th overall, 1 season, got to see more), Lamar Jackson ( 32nd overall, regular season MVP, irrelevant in the playoffs), and Mahomes.
And it gets even uglier when you get out of the first round. Fox Sports ran the numbers already. Until find your franchise QB you need to keep drafting one because the QB purgatory we've been stuck in sucks. Not good enough to win a playoff game but not bad enough to land a top 3 picks.

We're also not talking about letting Dennis Allen trade up to #1 overall to find his QB. We're talking about a brilliant offensive mind and former QB trading up. If he thinks Ward is worth it then chances are he's worth it. Most QB's bust because they are going to a system that doesn't fit them or they aren't mature enough to handle it. We don't have to worry about the system with Moore and they're doing their HW to figure out the maturity question but that's supposed to be a positive with him.
