Entering Wednesday, the National League East was the only division that had three teams in position for either a division title or a Wild Card berth.

The Braves sat atop the division, while the Nationals held the first NL Wild Card spot and the Phillies were tied with the Cubs for the final Wild Card berth. Thus, it's no surprise that the NL East was one of the busiest divisions leading up to Wednesday's Trade Deadline.

Atlanta made substantial additions to its bullpen, Washington made a flurry of moves to patch up its own 'pen and Philadelphia continued its recent trend of making minor upgrades. The Mets, meanwhile, held on to both Noah Syndergaard and Zack Wheeler, while even the Marlins got in on the action, acquiring the D-backs' top prospect.

With this year's one and only Trade Deadline now passed, here's a look at the biggest question still facing each NL East club.

Braves: Is the rotation strong enough?

Though the Braves significantly upgraded their bullpen, they did not find a suitable deal to solidify their rotation. Mike Soroka and Dallas Keuchel serve as strong anchors, and Julio Teheran’s stock has risen as he has allowed two earned runs or less in 14 of his past 16 starts. But there are durability concerns regarding Soroka and Max Fried, who has recently faded. Kevin Gausman will attempt to prove key down the stretch for a second straight year. The addition with the most potential to influence this rotation would be Mike Foltynewicz, who needs to regain confidence and consistency in his slider before being given a chance to return to the Major League level.

Marlins: Who will fill out the big league rotation?

To land three high-end left-handed hitting prospects -- Jazz Chisholm, Jesus Sanchez and Lewin Diaz -- the Marlins tapped into their pitching surplus. Now that Zac Gallen is no longer in the rotation, who is next in line to round out the staff? Triple-A New Orleans right-hander Robert Dugger is a candidate, and so is Hector Noesi. In a few weeks, Pablo López (right shoulder strain) is expected to be back. For now, he’s on a rehab assignment at Double-A Jacksonville. Lopez eventually projects to get the nod, but he must first establish that he’s healthy.

Mets: Can they actually compete for the postseason?

The Mets made a minor gamble prior to the Deadline, sacrificing two of their better prospects to add Marcus Stroman to their rotation, while doing nothing to restock a depleted farm system. In doing so, they kept their chances of competing for an NL Wild Card berth alive, despite trailing by six games in that race at the time of the Deadline. If the Mets can continue to take advantage of a soft schedule into mid-August, they’ll likely consider it a worthy gamble. If not, they may regret not acquiring value for Wheeler, an impending free agent.

Nationals: Is the new-look bullpen good enough?

The Nationals did not make a big, splashy addition to their beleaguered bullpen, instead adding three solid relievers to a group that's been short on those for the entire season. But will it be enough of an improvement for a bullpen that has carried the worst ERA in the Majors for most of the season? And what roles will Daniel Hudson, Roenis Elias and Hunter Strickland play in manager Dave Martinez's bullpen? Those are all questions that will be ironed out in the next two months as the Nationals hope to reach the postseason, after betting this trio of relievers will bridge the gap to closer Sean Doolittle much more smoothly.

Phillies: Can the bullpen do the job?

The Phillies tinkered with their bullpen before the Deadline, but did not address it like the Braves and Nationals. Both of those teams added three veteran arms for the stretch run. The Phillies instead added right-handers Mike Morin and Blake Parker, and moved former starters Nick Pivetta and Zach Eflin to the bullpen. They are banking on some of those arms panning out, complementing closer Héctor Neris and the left-handed trio of Adam Morgan, José Álvarez and Ranger Suárez. Pivetta might be the key. He has late-inning stuff, but has never done the job before. If he can make his high-octane fastball and sharp breaking ball work in short stints, it would do wonders for the Phillies.
