Run scoring and run prevention are each half the game, so pitching plus defense equals 50%, meaning at most, defense is 10-15% of the game. SL has two terrible defensive OF's, range-wise at least, and the "good one" throws like Juan Pierre. The funny thing is, the Brewers are in the upper half of both UZR and DRS, yet many insist they are terrible...because they see it with their own eyes. That's the exact same argument they used in favor of metrics a few years ago, because they claimed the eye/scouting was biased. An e-mailer told me the other day the Brewers were actual best in the majors at DE in the 2nd half of the season. I think DE is a junk stat myself, as it seems to correlate nearly 100% with LD%, but some use it. Most every team in MLB, save the Rays, are within a couple wins of average defense. Add up all the above, I'd continue to build with pitching and offense, and focus on making the routine plays and hitting the cutoff man.
