Someone mentioned that if Roberts loses this series, he will be fired. I tend to agree. One can argue whether or not he's a good manager, but he definitely is a class act.
I'm not sure he's burnt out. Like I posted earlier, he seems to be less intense when it's not an actual save. He was pretty much like that during the regular season.
Kimbrel is a legit closer; he's just not the closer he used to be. In his defense, most closers don't last as long as Kimbrel has. I doubt he'll be back next year, but he was a big factor during the regular season.
