Rondon and Nathan weren't going to help this team. And why no mention of Alex Avila? Or even Kyle Lobstein? Their absence were more of an issue.
The Cardinals have had Holiday, Garcia, Lynn, Wainwright, Jay, Belisle and Adams on the DL. Yet, they have the best record. However, now it appears Yadier Molina is out, which can effect their playoffs.
Sometimes, teams win because they are lucky not to have any injuries to key players (KCR). Sometimes, teams lose key players (2014 TEX) and rebound the next year (2015 TEX).
The Mets are winning this year, without David Wright for most of the season and Zach Wheeler. Parnell, Gee, d'Arnaud, Daniel Murphy, Duda, and Cuddyer have spent time on the DL.
While some teams can weather the storm, DET hasn't. DET was last in 1st place on May 16th. Since then, they have been the worst team in the AL by 3 games on OAK. That isn't weathering the storm, that is total collapse. Luck has nothing to do with not having replacement level players in the minors. When you have to sign or trade for players like Wolf, Krauss and Feliz, luck is what you are hoping for.
