Then you have to worry about the league saying the saints knew better and that they colluded with Brees to skirt the system.
But, if that’s their intent, you can play it out further by putting Drew on PUP to start the 2021 season. Doesn’t he need labrum surgery or something like that? It would legitimize the salary move, and give the Saints the option of running with Jameis, Taysom or someone else to see how things go. Drew could play the roll of ace in the hole, only if needed.
Might as well have the option of using him in a pinch. It would be a creative approach to maximizing dead money.
