1. Does the light come on for Ryan Tannehill?
If he’s great, this is a playoff team. If he’s not, uh-oh time for the entire organization, from Jeff Ireland on down.
2. Will Mike Wallace provide the offense’s missing spark?
If he’s as good as he was in 2010 — more than 1,200 yards, 10 TDs — the $30 million in guarantees will be money well-spent.
3. Can the pass defense hold up its end of the defensive bargain?
Miami had one of the most picked-on secondaries in football last year. But that was before Brent Grimes joined up. He’s a difference maker.
4. Will the Caleb Sturgis gamble pay off?
Miami dumped established veteran Dan Carpenter for an untested rookie. Gutsy move for a team involved in eight close games last year.
5. Will the offensive line give Tannehill time to shine?
Jonathan Martin, who’s replacing Jake Long, has shown encouraging signs. The right guard position, however, was a mess in preseason.
6. Who will have more rushing yards: Lamar Miller or Daniel Thomas?
It was a good battle for the No. 1 job throughout camp. But even if Miller wins it, he must prove he can stay healthy.
7. What will the Dolphins get out of Dion Jordan?
The No. 3 overall pick has gobs of potential, but the fact that his rebuilt shoulder still gave him problems during camp is worrisome.
8. Can one of Miami’s young tight ends step up?
Dustin Keller’s knee injury was a punch to the gut. But Miami has spent draft picks on the position in each of the past three years.
9. Will Cam Wake win the Defensive Player of the Year Award?
He was in the conversation in 2012, and now has more help than ever. Wake could threaten the franchise’s single-season sack record (18.5).
10. Will fans return to after historically low attendance in 2012?
See questions 1-9. If the Dolphins win, they will.
