During a conversation on Thursday morning’s “Bernie Show” on 101 ESPN, Cardinals president of baseball operations John Mozeliak dropped a hint. Something could be stirring. I was intrigued. Would it be a trade? Maybe a free-agent buy? Mozeliak’s comments were made during our discussion on the Cardinals’ bullpen. For a while now, I’ve believed the reliever emergency unit lacked depth, and strength and required more arms. Mozeliak disagreed, but wasn’t dismissive of the opinion.
