What are you talking about? They brought in 4 veteran receivers (G. Little, Salas, Boykin & Hankerson), all of which had experience starting on other teams. Of those, they decided to keep Salas and then he got injured. Other than Hankerson's drops in preseason, We don't know what was behind the decision not to keep any others. It wasn't like they didn't bring in anyone, or just undrafted free agents. Powell impressed in training camp and preseason so they decided to keep him.
