I wouldn't trade any of them except for Brees.
All of those teams have a chance to win 1 or multiple superbowls in the next 3-5 years with their current QBs, While Luck is very good right now which of those teams can win a Superbowl with him right now? The answer is none of them.
Your job as a GM doesn't last 10 years if your team is not a Superbowl team right now, unless you're AJ Smith.
I would trade Brees, because the Saints have a ton of holes that need a couple years of drafting to fix.
