Really not sure where the roster instability theory is coming from. We have been almost entirely stable at every position besides CF and 2B. Broxton hasn't built on his 2nd half last year as hoped, but he's not the awful black hole that people like to make him out to be. Brinson and Phillips unfortunately haven't shown readiness to produce at the MLB level, yet. Villar has been pretty bad, but they did a good job calling up the right guy in Sogard and taking advantage of his bat while it lasted, which unfortunately looks to be gone now. But coming into the year, given how good Villar was, we appeared to be well set at 2nd. The rotation has been rock solid. There hasn't been much instability there in months, other than Guerra being demoted which I think we can all understand. Any other instability has simply been the result of injuries. The most unstable part of the team has beem the pen, for obvious reasons, and I think most are in favor of the roster churn there.
