I suspect it's the high heat and that Kelly has at times.... looked crazy dominant... like future shut-down closer for team with playoff aspirations type dominant. I don't think that potential is there with Velazquez at all. And who knows? Catch lightning in a bottle! He could find some movement on that 100mph fastball and end up in a Scott Williamson role circa 2003 playoffs (WHY GRADY WHY?!?!?!?).Velazquez has an ERA of 3.18 this year, Kelly 4.39. They are both right-handed and both struggled at various times late in the year. What are the fancy stats that make Kelly the better choice?
edit- what bosox79 said with more stats and less anger.
