It's hard to say that injuries are the main reason for a team's struggles. Every team has to deal with them, and it's the good teams that are able to make up for missed time. But what the Mets have had to deal with over the past few years is ridiculous.
Back in May, Ike Davis suffered what appeared to be an innocent bruised ankle when he collided with David Wright on a pop-up. That innocent bruise turned into a season-ending injury. David Wright missed a substantial amount of time with a back injury, and Daniel Murphy suffered an excruciating knee injury in August.
Jon Niese was having a good season until he suffered a rib injury in August, and righty Chris Young has missed essentially the entire season with a shoulder injury. I also mentioned that the Mets have been without their ace Johan Santana, and prospect Jenrry Mejia, for the entire season.
For the first half, the Mets were able to send out a patchwork lineup with young infielders like Justin Turner and Ruben Tejada stepping up. But you can only survive so long without so many of your top players.
So while this was a tough season, I feel like Mets fans still have a lot to look forward to. With a healthy and focused lineup, a fortified starting rotation and a smaller Citi Field, the Mets can be a quiet contender in the National League next season.
