This is the point I was trying to make in another thread recently concerning VV/Anderson/Moore (and the lack of any realistic upgrade currently behind them). I realize the statement may have been a bit stat-laden given the current season's sample size, but I was accounting for past performance trends and where those paths were leading them respectively this season as well.
You directed me, after my previous post there, to focus more on the pitcher's stuff than statistics - certainly a valid point, but also something I'd already looked at as well. My thoughts there were, as you stated here, that Anderson and Moore were going to have to be extremely accurate in order to be effective.
The definition of 'effective', 'not terrible', etc. will vary by user, but I'm looking for the club to move past the .500 mountain they've been scaling the past three seasons. There are many areas we could point to to help with that climb, but my mind has been stuck (for better or worse) on the back of the rotation and bullpen. The frustration is I don't have more in the way of answers, something I like bringing in kind to any host of concerns/complaints.
