What to watch at Dolphins camp

DAVIE, Fla. (AP) - The Miami Dolphins finally have the go-to

receiver they've long sought. They're set at quarterback with

second-year starter Chad Henne, and Jake Long returns to anchor the

offensive line.

But plenty of other starting positions are up for grabs as

training camp begins Friday.

There's a void at free safety, three cornerbacks will battle for

two jobs, and the defensive front seven is being revamped following

the departures of Jason Taylor and Joey Porter. The offensive line

faces a makeover, competition at the receiver spot opposite

newcomer Brandon Marshall will be fierce, and even injury-prone

Ronnie Brown faces a challenge for playing time at running back.
