Clay Buchholz is back pitching full time in the Red Sox starting rotation.

But if the Sox are seriously thinking about adding Aaron Cook to the staff by his May 1 opt-out date, isn't the spot they'd have to consider taking Buchholz's?

The Sox appear hell-bent on not moving Daniel Bard back to the bullpen. So if Bard remains a starter and the Sox want to accommodate Cook, someone has to be dropped.

It's probably not fair to remove Felix Doubront, who is on a steady climb.

And so if Buchholz stays, Cook probably won't - unless he's added as a bullpen piece, which also doesn't seem logical.
