After you take out the head-to-head matchups (Brewers vs. 2008 opponents), the weighted average win% of the Brewer's opponents (weighted by how many times the Brewers have played them so far) so far is .548. Being only 38 games into the season, however, that number does not do a good job representing the actual talent level of each team. A better way to estimate a true teams' talent is to look at the current year's record AND the preseason expectations. For instance, Florida is not going to win win 98 games (their current pace), so why should we pretend that they current record represents their true talent? Even though the Mets are only 2 games over .500 right now, we expect them to do better than that going forward because we expected them to do very well going into the season. What I did was take each Brewer opponent's adjusted win% (win% after the Brewer games were removed) and regressed that 80% towards their preseason projected win%. I called that the "true talent win%" The weighted true average win% of the Brewers opponents so far this year is .500 on the dot. perfectly average. The Brewers have played 21 of their 38 games on the road, though, so their schedule so far has been a bit harsher than average. Wow harsh? If we thought the Brewers were a perfectly average team, we'd expect a 18.8-19.2 record from them. Some other expectations ("wins" just means how many wins the Brewers should get with a neutral schedule. Their true talent level): 81 wins: 18.8 - 19.2 81 wins: 19.1 - 18.9 86 wins: 20.0 - 18.0 90 wins: 20.9 - 17.1 Based off of preseason expectations (offense being able to hit, Gallardo in the rotation, Gagne not being terrible), the Brewers should have about an extra win. I have no idea why I'm supposed to act outraged that the Brewers are 19-19 right now.
