I don't know. There's been a lot of attrition and some guys we never saw play much. I mean, Carson Butler had a lot of talent but couldn't earn playing time under Rodriguez. I know he was an asshole, but he was a talented asshole. Lloyd had a knack for developing wide receivers. Perhaps Mathews, Clemons, or Hemingway would have been studs if Carr were still here. Maybe O'Neill would have stuck around and Carr's offense would have fit him better.
I don't know. It's impossible to tell.
