I know next to nothing about RAS scores but using it as a metric seems to be as effective as any other for drafting and according to this site the Saints ranked 3rd in the 2023 draft. Hopefully that means some of the picks people are worried about have legitimate shots of making an impact on this team. i couldnt find a more comprehensive coverage of it, this was the only link I came across listing the top five cumulative grades. Another thing of note is the the Broncos and Payton were just behind the Saints in this metric so I am guessing Payton puts some weight into it as well. https://www.nbcsports.com/chicago/bears/what-ras-everything-you-need-know-about-draft-metric
