Using Senzatela as a reliever makes more sense to me than Marquez. I agree that Marquez is one of their better starters and needs to stay in that role. Senzatela had a nice year as a starter too, but they were always talking about how he's basically a two-pitch guy who relies heavily on the fastball, and that is very reliever-esque. I worry that without another good pitch, as a starter he'd make it through fewer and fewer innings as hitters continued to figure him out.

Like you, I definitely want them to bring Neshek back, and I wouldn't mind if they made an offer to McGee too. He pitched well last year and stayed healthy. If Holland would agree to a two-year deal I think even at his price that would be good for the Rockies, but I'd be really nervous committing to a 3 or 4-year deal along the lines of the Melancon contract. That's too much risk if Holland never ends up bouncing all the way back from his surgery (which I don't think will be the case, but it's a possibility).
