Saints at the top of Davante Adams’ wish list [Raiders trade Adams to Jets for conditional 3rd ; Jets paying Adams’ entire remaining salary]

Starting caliber centers are not sitting on teams practice squads. His starting experience is on terrible Broncos and Jets teams and he was never on a team that was better than 7 wins in his 7 years as a pro. And he's wasn't good enough to be on any teams roster before we got desperate. We are scraping the barrel.
Well yeah, you think you can do better? Who do you suggest then? And how would we obtain him?
