Let's compare by position: 1B - .266/.337/.437/.774 - Lee/Ward should beat that OPS by 100+ points 2B - .274/.326/.411/.737 - Expect at least this production if DeRosa reverts to career number, a bump of 50+ points in OPS (particularly OBP) if DeRosa plays closer to 2006 number and Theriot sees some decent PT. SS - .246/.275/.324/.598 - As bad as Izturis' bat is, his career numbers are better than this line. (631 OPS). It's not unreasonable to expect some combination of Izturis/Cedeno/Theriot to bump this OPS by 20-30 points. 3B - .282/.340/.544/.884 - ARAM had 592 ABs last year. There's as much reason to expect a small decline (e.g., a DL stint) in 3B production as any improvement. My guess is 0 to -40 points of OPS. C - .287/.341/.473/.814 - I'd expect 50 or 60 more ABs out of Barrett (10-game suspension and DL time), on the other hand, Blanco was not as bad offensively in 2006 as he usually is. Call it a wash. LF - .280/.346/.428/.774 - Murton and Floyd should both improve on this line. My guess is 50+ points of improvement in OPS (mostly coming from SLG). CF - .294/.333/.393/.725 - Even if Soriano reverts to career numbers, he beats this line. Expect at least 75 point of improvement in OPS (almost all SLG). RF - .288/.337/.498/.835 - we might see regression here. If JJ reverts to norm, you might lose 60 points of OPS, but how long does that go on before DeRosa's platooning in RF? Or Pie is brought up? My guess is -30 points of OPS. So overall, while OBP isn't likely to improve nearly as much as the Cubs need it to, the overall bump in OPS could be 250 or more points. That's like replacing Izturis in the lineup with Scott Rolen or Andruw Jones. Pitching? 1 Zambrano 214 IP, 1.29 WHIP, 3.41 ERA 2 Maddux 136, 1.29, 4.69 3 Marshall 125, 1.52, 5.59 4 Hill 99, 1.23, 4.17 5 Marmol 77, 1.69, 6.08 Starters overall: 5.19 ERA Relievers: 4.04 ERA It's not hard to imagine that Zambrano/Lilly/Hill/Marquis/Prior/Miller/Guzman could put up significantly better numbers this year. The roster improvements are enough to get the Cubs to respectable (.500) and in contention (85-90 wins) with some luck.
