Actually, Mel Kiper Jr. re-graded every team's 2014 draft in this Insider piece here. But since this is a New York Giants blog, you're interested in what he thinks about the Giants' draft in particular. He likes it.

Mel liked the Giants' draft in the first place, giving it a "B" immediately after it was over. Since this is an Insider piece, I'm not going to tell you here what the re-grade is. But considering they got 12 rookie-of-the-year-caliber games from first-rounder Odell Beckham Jr., 15 starts from second-rounder Weston Richburg, a team-leading 721 rushing yards from fourth-rounder Andre Williams and 4.5 sacks from fifth-rounder Devon Kennard, you can assume the grade improved upon consideration of the season's worth of evidence.

The Giants desperately needed a strong 2014 draft, after years of unproductive ones, and the early returns indicate that this could be the most productive since Jerry Reese became GM in 2007. If Williams can be a starting running back, Kennard a starting linebacker, Richburg the team's center of the future and Beckham the kind of star performer he was as a rookie, there will be no doubt.
