Dolphins general manager Jeff Ireland isn't happy with the look of his backfield. Miami drafted Kansas State bruiser Daniel Thomas in the second round and both Ricky Williams and Ronnie Brown are free agents. "I'm interested in having another back, whether it fits the description of a scatback or not, we'll have to see what's available. You can't corner yourself into just a scatback," general manager Jeff Ireland said. What this means for veteran incumbents Ricky Williams and Ronnie Brown is unclear, but it doesn't sound promising for either. "We need another complementary back who complements Daniel [Thomas] and Lex [Hilliard]," he said. "We do have somewhat of a scatback in Kory Sheets that we haven’t seen yet, so I'm still hoping he can develop."
