Craig Kimbrel and Dallas Keuchel remain unsigned. They are fine ballplayers. Either one could help any of the 30 teams, though the price those teams are willing to pay for their services has obviously remained a barrier, and the two pitchers remain drifting about in free-agent land.
One hurdle to their employment that has perhaps been under-reported is that both players turned down a $17.9 million qualifying offer from their previous team. That means the signing team must pay a draft-pick penalty, which varies depending on that team's financial status. It's worth noting that all first-round picks are now protected unless a team has multiple first-round picks.
