Total offense: .272/.342/.429, 160 HR, .338 wOBA
In 2008, the O's hit .269/.333/.429, 172 HR, .340 wOBA so things don't look all that different. Huff and Mora probably won't repeat their '08 seasons, but the additions of Wigginton and Wieters help. A bit above average again, while putting a plus defense on the field (especially in the outfield).
Pitching total: 4.73 ERA
Last year it was 5.15 so that's a big improvement. It's not really "better" though, as it's really hard to pitch that poorly (5.14 FIP too) two years in a row. Only two guys in the rotation with ERA's under 5 (Guthrie and Uehara) would make games hard to watch most days, so hopefully they can stay healthy all year. And there's a decent chance that someone (anyone, please) actually lucks into a pretty good season. Alternately, it's likely that one or two guys put up an ERA above 6. The idea is that those guys get replaced quickly (if the ERA is deserved) by someone who is less bad.
Overall, that team has about 78 wins worth of talent based on Wins Above Replacement. Given that they play in the AL East I would personally be inclined to knock another win or two off of that number, but a 75-77 win season is what I'm looking at. And no September collapse would be nice.
