The much-anticipated cornerback competition for the spot opposite Will Allen will begin on time. The Dolphins have agreed to terms on a five-year deal with first-round pick Vontae Davis, an NFL source confirmed this morning. When training camp opens Sunday, Davis, the No. 25 pick out of Illinois, is expected to compete for the right cornerback spot with second-round pick Sean Smith and free-agent pick-up and fifth-year pro Eric Green.
