New Orleans Saints defenders will likely be more fundamentally sound under new coordinator Dennis Allen than they were under Rob Ryan, NOLA.com | The Times-Picayune NFL scouting expert Chris Landry said in our latest Scout's Take podcast.

How will that impact the unit's league-worst ranking? Not by much, he said.

"He's not going to turn water into wine," Landry said. "This is not a very talented team. I think from a fundamental standpoint, they could play a lot better. A lot better focus, a lot better technique."

The Saints fired Ryan on Monday, one day after a 47-14 loss at Washington that stood as the most lopsided defeat in the Sean Payton era.

"I don't know if you're going to see much of a statistical difference with the personnel that they have for the rest of the year," Landry said. "I think you will see a little bit more sounder gap control, a little bit more technique use in coverage. Just a little bit ... a different approach. A little bit more cerebral. He's a guy that will get into your face, but he's a guy that is a little bit more into explaining what needs to be done how and why. So I think from that standpoint we could see some improvement, but again I stress that the personnel is a bigger issue and you can't make miracles out of it."

That talent deficiency "was only made worse by how Rob tried to play it. It's not that Rob is a bad coach. He didn't have the talent to do what they wanted to do.

"It must be said, the defensive coaches, this is an organization where the coaches make the personnel decisions. The defensive coaches have a lot to do with the signings and the moves. ... Quite frankly some of those guys didn't work out. Some of those were a bust."
