If you never DFA players, and you have guys sitting in AAA that are better, you can't improve the team as it sits currently.
We are about to embark on the playoffs, this isn't a time to remain loyal to players that are not helping you, in any way at all. Just because we traded for Chafin doesn't mean we should continue to roll him out there. He is just plain bad, and has cost us games. I know Rowdy is a fan favorite (or was) but outside of the sac fly he provided us recently, what has he done before his injury, and more importantly, after his return. The guy is plain dead weight. Anderson is an entire different animal. He is obviously in CC's doghouse, and if we aren't going to use him in situations that warrant it, then why have him on the roster at all.
There are justifications for standing pat, and there are justifications for making moves. We need to do what is best for the team in a playoff push. End of story.
