Joe Rose and Dave Hyde discuss what they're looking for as Dolphins training camp approaches, explaining why someone on Miami's roster needs to emerge as a difference-maker this summer. The guys look back at past Dolphins experiments, including high-profile additions like Ndamukong Suh and Mike Wallace, and why simply adding talented players doesn't always guarantee success. They also praise the Dolphins' decision to bring in a new general manager and give him full control over personnel decisions, debate whether Chop Robinson is ready for a breakout season, and examine the inexperience at cornerback that could create major opportunities for Miami's young players to earn significant roles.
