I agree that its a draft and develop team. IMO, there are just so many young guys on the roster that some of those 4 will be gone to make room for OTHER development people.
Just as an example: Richards. The team has Tyler Smith, Guyton, Bass, Richards and Beebe as 1st or 2nd year lineman. That's a LOT of youth. I think its either Waletzko or Richards for the #9 guy on the roster.
Eric Scott? Cowboys have a pretty deep defensive backfield. They just signed Conley and drafted Carson. IMO, its Scott or Nashon Wright for the last DB spot.
Fehoko? He is behind Micah, Kneeland (R), Tank, Williams on the DE list and the team also likes Tyrus Wheat (2nd year). Fehoko is at a minimum going to have to beat out Wheat to make the roster.
These guys may end on the practice squad.
