The best thing the Saints could do by Alvin Kamara is to trade him to a contender.

Yep. And as much as it pains me to say it, they did the same with Drew Brees. I get why they did it and the team and the City of New Orleans owe him everything so I don't hate them doing it, but the smart move would have been to tell Drew he needed to retire or release him when Brady was willing to sign with the Saints.
id rather lose for a dozen seasons in a row than replace Drew with Brady
