Here is the thing with Edmunds. Him and Milano are exact same skill set. Good sideline to sideline that are not aggressive at POA (Milano is a bit better here). What I think the Bills are looking for here are same coverage and range ability but more violent at the point of attack. And more stout at POA. That is what Sal means by thumper.
can either of the two former rookies Benard or Spector or even Dodson fill that eventually? I think that would be their plan. But look at an older type player that also fits that mold to come in and teach the Benards Spectors Dodsons or Rookie in the twilight of their career.
