The Advocate’s Saints beat writer Nick Underhill hits the nail on the head about draft grades.

“I think draft grades are worthless. They’re fun to read, but it really doesn’t matter what letter someone attaches to your grade,” he wrote Sunday.

Without assigning a letter grade, Underhill continued in his Sunday analysis, saying, “I like the idea behind most of these picks. The Saints took a measured approach to this draft, let the board come to them and pounced where they needed to pounce.

“The big trade up is appealing to fans on draft day, but that’s not a healthy way to build a franchise.”

How did national experts view the Saints’ draft? Here’s a sampling of their analysis.

ESPN’s Mel Kiper

Grade: C

Summary: Andrus Peat hits a need on the offensive line, but he's probably not ideal as a starter in Week 1 because NFL-level pass-rushers could give him fits ... Though (Stephone Anthony) hits a need, I had a trio of inside linebackers ahead of him on my board. Not a big fan of the move. Hau'Oli Kikaha is another reach on my board ... A sleeper here could be Davis Tull.

USA Today’s Nate Davis

Grade: n/a; ranks Saints’ class No. 6 in league

Summary: Sure seems like they got a needed injection of size and toughness and telegraphed an intent to do exactly that…

SI.com’s Doug Farrar

Grade: B-

Summary: The Saints took a few prospects who had observers raising their eyebrows. First-round offensive tackle Peat might be the best pass-blocker in his position group … Hard-pressed to call linebacker Stephone Anthony the best inside guy this year. Second-round pass-rusher Kikaha is an outstanding technician who might surprise …

NFL.com's Bryan Fischer

Grade: C

Summary: Andrus Peat could wind up being the best player at left tackle in this draft class … Saints reached for Kikaha, but there's little doubt he will be a boost to the pass rush.

CBSSports.com’s Pete Prisco

Grade: C

Summary: The Saints indicated Peat might not start in 2015. That's weird. Anthony is a reach as their other first pick...

Washington Post’s Mark Maske

Grade: B+

Summary: This is a deep and interesting draft class for New Orleans. Anthony, Kikaha and defensive back P.J. Williams, an excellent third-round value, all should help right away on defense … Saints had an abundance of early picks and used them relatively well.
