I'm not sure if they can. I should've clarified and articulated my thoughts better. A plan will be decided on, or by draft day at the latest. It's entirely possible that the Saints and Steelers (or another team like the Browns) "start talking" on a trade and that trade is officially executed June 2nd. Clearly in this case, any compensation would be for 2026 draft. It's not common but we've seen it done before more then a handful of times. over the last decade or two.
No matter how it plays. Underlying moves/actions from Carr and Saints FO hints to Carr not being under center week 1 for the saints.
