For several years now, my good friends Andrew Kapral, Trevor Sierra and I have made several statistical predictions about each upcoming Cubs season. Since 2007, Andrew has won our little competition twice and tied another time, Trevor has tied once, and I've won once.
We always predict how many games the Cubs will win and have continued to predict how many games Zambrano will win purely for its comedic value as we typically overshoot it to an absurd degree.
We've got a few new ones this year, including our first truly sabermetric prediction thanks to Andrew.

From FanGraphs: Weighted Runs Created (wRC) is an improved version of Bill James' old Runs Created (RC) statistic, which attempted to quantify a player's total offensive value and measure it by runs. This way, instead of looking at a player's line and listing out all the details (e.g. 23 2B, 15 HR, 55 BB, 110 K, 19 SB, 5 CS), you could synthesize all the information into one metric and say, "Player x was worth 24 runs to his team last year."
