Almost through his fourth full season with the Boston Red Sox, Dave Dombrowski, President of Baseball Operations, was fired, coming off of a World Series Title winning season.
Looking at the situation objectively, he led the team to win the American League East Division three seasons in a row and also won a championship—a seemingly impressive tenure. There is no debating that, however, Red Sox fans will be left with a terrible taste in their mouth by how his time in office came to an end. Perhaps Dombrowski’s legacy will improve in the future after all is settled down, but for now, it certainly is tarnished. 
In August of the 2015 season, Dombrowski was hired with the intentions of building a World Series contender. His tendency has never been to rebuild—it has always been to go out there and find proven talent, behaving in win-now mode. He proved this, as the first thing he did was sign David Price and trade for Craig Kimbrel, followed by trading for Chris Sale the following season in 2017. These moves amounted to consecutive division titles, but also back to back first round playoff exits. That is when Dombrowksi hired Alex Cora, prior to the 2018 season, just as he signed J.D. Martinez. The Red Sox had a historic season in which they won 108 games and cruised through the postseason en route to the title. 
This set up a golden opportunity for the Red Sox to be the first team since the early 2000 Yankees to win back to back World Series Championships. However, for some baffling reason, Dombrowski felt no need to improve the Red Sox already suspect bullpen in the 2019 off-season. In fact, both Craig Kimbrel and Joe Kelly left in free agency, and the team decided to just roll with what they had left. Yes, they were able to overcome the poor bullpen in the 2018 postseason, but it was bold and dismissive to assume they could survive it through a full 162-game season. Sure enough, the Red Sox have blown nearly 30 saves, and Dombrowski has been left without a job. To, essentially, not show up to defend their title is something Red Sox fans should feel very frustrated about and should not take lightly. 
The next step for the Red Sox is to look for their new general manager/president of baseball operations. There is a plethora of candidates, but it is tough to predict what direction ownership will decide to go in. If it were up to me, this is an easy decision because there is one guy perfect for the job, and that is Theo Epstein. Sure, his time here did not end on great terms either. Yes, he currently is still the general manager of the Chicago Cubs. With that said, there has been plenty of talk of him wanting out of Chicago, and there is a real chance he becomes available. Even if not, they could always make a trade for him. The bottom line is that the Red Sox are in an interesting situation. Their farm system is almost completely depleted, while a bunch of their stars have upcoming expiring contracts. As previously stated, Dombrowski is known for getting rid of potential talent while bringing in proven talent. On the other hand, Epstein is known for discovering potential talent and developing players at an insane rate. He completely revamped the Cubs system and won them their first title in 108 years. While being able to draft and develop, he still knows when and when not to pay veterans. Put Theo Epstein back in the Red Sox front office and you will see Boston right back in the running for best team in Major League Baseball.
