After four straight fourth-place finishes, and with a dominant NL East staring them in the face, there are plenty of questions surrounding the Mets.

While general manager Sandy Alderson walks the tightrope of trying to simultaneously rebuild and compete, here are some of the biggest issues facing the team.

Most important story in camp

Is the Mets’ young pitching really talented enough to resurrect the franchise? Matt Harvey was dominant for the final two months of last season and Zack Wheeler is a stud prospect, but both have plenty to prove.

Best position battle

Center field and right field are wide open, with Kirk Nieuwenhuis, Collin Cowgill, Andrew Brown, Mike Baxter, Jordany Valdespin and Marlon Byrd in the mix.

Most intriguing rookie or minor leaguer

Travis d’Arnaud was the centerpiece of the R.A. Dickey trade to Toronto and could end the revolving door the Mets have had at catcher for several years.

Story to develop

If Wheeler shines in spring training, how long will the Mets keep him at Triple-A? Or will Wheeler have a shot at making the Opening Day roster?

Manager’s toughest challenge

If the Mets start slowly the whispers about his job security will turn to shouts. Collins is in the final year of his contract.
