Cardinals beat writer Kent Somers talked about the team's WRs:
Is Andre Roberts likely to keep his starting job?
My guess is yes. Coaches think he's developed into a good player and that his statistics last year (51 rec., 586 yards, two touchdowns) were more a reflection of problems at quarterback.
Michael Floyd, the first-round pick, will not immediately step into the starting lineup. In fact, I'd be surprised if Floyd is ranked above Roberts or Early Doucet any time soon.
