As long as he's Miami's quarterback, Ryan Tannehill will play in Dan Marino's shadow. Someday, he hopes to cast his own. Tannehill, surrounded by more offensive weapons in his second NFL season, passed for 272 yards and a touchdown, leading the Dolphins to a 23-10 win on Sunday over the Cleveland Browns, who lost their ninth straight opener and fell to 1-14 in Week 1 since 1999.
