Aaron Cook supposedly has a sore shoulder. Not good. Not good at all. Granted, the grinder is struggling lately, but if he's not right, the Rockies will significantly suffer. Cook is no star but he is usually dependable. The problem is who replaces him in the rotation?

Honestly, there are no easy answers to that problem.

Jhoulys Chacin, down in Colorado Springs, despite his stellar first outing in Triple A, is not ready for prime time yet. He will be, he just isn't now.

Recycled Adam Eaton? Forget what he's done in the minors this season and his relief work in Denver, he's not a quality starter. Look at his history.

Josh Fogg? He's done it before and the most likely guy to replace Cook but he was awful in Cincinnati after leaving the Rockies. He is much better suited to being a reliever at this stage of his career than a starter, even a 5-inning guy.

Answers?

There are none because this franchise doesn't have enough pitching depth and the Triple A roster is lacking in pitching. Double A isn't the answer either.

Fogg or bust.
