Dan O'Dowd and the Rockies do little more than find zen in the Winter Meetings according to the official site, and our GM realizes maybe three pieces for Jennings is too much:
If the Rockies trade Jennings, who could leave as a free agent at season's end to test a skyrocketing starting pitching market, O'Dowd said they'll need a younger starter "with some upside" to replace Jennings' ability and durability, and they'd need an eighth-inning setup man. They figured early on that trying to get those two parts and a center fielder was impossible.
I'm happy with that. According to the report, the Rockies would have targetted Joakim Soria if he hadn't already been snagged by the Royals in the Rule 5 draft this morning.
