Agree 100% with those pointing out that the Steelers have 9 draft picks, and most of those are pick 83 and later. In my opinion the Steelers should package their two 3rd round picks to move into the middle of the 2nd round. Pick 66 from the Raiders has a value of 260 points, and pick 83 has a value of 175 points for a total of 435 points.
The equivalent point value is pick 46, the 14th pick of the 2nd round. That would give the team 3 picks in the top 52.
Take a look at the past 8 or so drafts, and see how many top-tier players were taken after pick 52. Hint - they are definitely out there, but are pretty rare. The Steelers for example have taken guys like Mike Adams, Sean Spence, Chris Rainey, Markus Wheaton, Shamarko Thomas, Dri Archer, Martavis Bryant, Shaquille Richardson, Jordan Zumwalt, Senquez Golson, Sammie Coates, Doran Grant, Jesse James, Leterrius Walton, Javon Hargrave, Jerald Hawkins, Travis Feeney, and the two very sterling picks later than 55 - Juju Smith-Schuster, a second rounder, and James Conner, a 3rd.
Point being that the myriad of picks 83 and later have a vastly reduced rate of return. Package those picks to target three impact players in the first 2 rounds - an ILB, a CB and a WR, for example. Or an ILB, TE, and CB.
