Jeff Duncan says, Saints are very interested in bidding for Xavien Howard.

No, they were not wrong for bringing in another CB. They were wrong for bringing in another lesser CB and making that lesser CB a top 5 paid CB. Look, I’m in my 40s and one thing that I’ve had to learn is that people can get their feelings hurt for the littlest things. In this case, I feel Howard has a legitimate gripe. There is literally no good reason why Byron Jones should be a top 5 paid CB. He’s good, but he’s not top 5 good. I can see that and Howard sees that as well. Jones’ best season is on par with Howard’s worst season (excluding Howard’s rookie year). Howard should be a top 3 paid CB in the league minimum.
I'm sure the Dolphins would've loved it if they could've signed Jones for much, much less but they couldn't. The market dictated his contract, not the team. Can't blame the Dolphins for the way the market works. There are players all over the league who are making top 5 at their position money but aren't actually one of the 5 best players. It's not just about talent, it's about when you sign. Just look at where these players are in the top 5 at their position:

Dak Prescott #2
Jared Goff #5

Keenan Allen #3
Amari Cooper #4

Hunter Henry #3
Jonnu Smith #4

Andrus Peat #2
