Leonard Williams is more talented than all of the defensive ends of the Redskins combined. Stephen Paea, Jason Hatcher, Frank Kearse, Ricky Jean-Francois? None of them would inspire the same fear that Williams would. Instead, they drafted Scherff who won't be able to stick at right tackle.
The thing that makes it even worse is that they already have Morgan Moses, whom they literally drafted to be a right tackle of the future, who was considered a high-second round pick in his class whom they practically stole in the third. Is Scherff going to beat out the highly-paid Lauvuo or Chester? I don't think so.
They wasted that pick, and they have absolutely no clue how to build a roster if they think that DeAngelo Hall and Chris Culliver are better options than Amerson or Breeland, that Leonard Williams wouldn't have been a better option than any of the ends that they currently have.
