First, I'll point you to a two part series at Trumble and Michigan where Sean Heyboer compiled the pre-season predictions of 25 bloggers.

First, there is Weighted On Base Average (wOBA). Invented by Tom Tango, wOBA is like OPS but it has more appropriate weights for different events and is thus a more accurate rate stat. It is called wOBA because it is scaled to look like an OBP. According to Tango, that means that .340 is about average, over .400 is outstanding and under .300 is very bad. It is calculated as follows:
wOBA = (.71 x BB + .74 x HBP + .89 * 1B + 1.26 * 2B + 1.58 x 3B + 2.02 x HR + .24 x SB -.51 x CS)/PA
The Tigers wOBA leaders in 2008 are shown below:
A statistic which is based wOBA is weighted Runs Above Average (wRAA). It is the number of offensive runs above average contributed by a player. These were the Tigers leaders in 2008:
The third statistic is weighted Runs Created (wRC). It is the absolute runs contributed by a player. It is considered by most analysts to be more accurate than the old runs created which overestimated the performance of great hitters. The top Tigers were:
