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

What does this have to do with trading Kamara? You’re comparing two completely different scenarios. You’re not happy if we pay veterans, but you’re also not happy at the idea of trading a veteran rather than paying him?

I think you missed his point. He's saying that the trade should be to whoever offers the most value. It should be restricted to trading him to contenders only.
