Dolphins RB Kory Sheets believes he’ll have a role in Miami’s backfield this season. “I will surprise people when I get on the field,” Sheets said. “I have everything Ronnie Brown and Ricky Williams had but more speed — 4.3 speed.” Sheets will enter camp no better than 3rd on the depth chart – behind Daniel Thomas and Lex Hilliard and is coming back from last summer’s career-threatening Achilles injury.
