Just like the collective offense, I think the problem with the players is not that they are inconsistent, but that too many of them are simply not very good hitters or are completely unproven.
How many players do the Brewers have in their everyday lineup that have an established record of good, consistent production over the last couple of seasons?
Counting on players who have never been productive hitters in MLB, or who have shown significant decline from past productive seasons, runs a significant risk of failure. And, over the last month or so, the Brewers offense has been a dismal failure to the point of being the one of the worst in the NL.
