There's two schools of thought on this, and I happen to belong to both:1. Heath Bell needed a third pitch, and was better served honing it in the minors.2. Heath Bell is better than Danny Graves and should have stayed with the big club.Look, we were never expected to contend this season. We're building a solid base for the future. And having Heath Bell become a better pitcher is only going to make us better in the long-term. Danny Graves should never have stayed here, but maybe, just maybe, this was a blessing in disguise.
