Well, if you agree that Weaver is going to improve, why are you riding him? Most teams would be delighted to have Weaver in their rotation. Like I said, the Cards have many, many bigger problems.
Wacha struggled and some posters right here wanted him traded. Before he was hurt, along with Mikolas, he was one of the team’s most dependable starters this year. Sometimes good players go through bad stretches.
Among relievers, demotion candidates would seem to be Brebbia, Mayers and Gomber. My guess is Munoz.
