It's hard to gauge that, though. Zambrano would be throwing fewer innings and pitches out of the bullpen. However, relievers are usually encouraged to throw harder and let loose compared to starters. My worry with Zambrano is that he'll let loose in relief and do something to screw up his mechanics or delivery, which could lead to a lot of problems when he returns to starting or, worse, injuries. I'm praying the Cubs keep a close eye on him and that he doesn't overdo it in relief. Yeah, it definitely couldn't be quantified, but my thinking was that the fewer innings could help Z stay healthier longer and slowing down the decline similar pitchers like Livan Hernandez hit. That's a good point on him potentially changing his mechanics, though.
