Dan Uggla's trade value

As you know, the Rockies have a lot of interest in your current 2nd baseman, Dan Uggla, and would make the team a lot better. However, I am wondering, what would Marlins fans want for compensation?

From what I've heard, two primary players of interest to the Marlins are Rockies catcher Chris Iannetta, who has been supplanted by Miguel Olivo, who is having a career year and is under a club option that is reasonably cheap for a quality catcher, and pitcher Jhoulys Chacin, a former top 50 pitching prospect who has had success in the majors. For those of you hoping to get one of the big three of the Rockies pitching youngsters (Chacin, Friedrich, Matzek), dream on. Chacin is penciled into the rotation next year due to his performance and is only in the bullpen because the Rockies can't get rid of their higher priced pitchers like Aaron Cook and Jeff Francis. Iannetta holds a big price because the Rockies don't want to give up on him because of Olivo's breakout year, but he is a trade asset because of the depth in the minor leagues and Olivo's breakout year (including an improved walk and K rate, so it's not like it isn't legit).

 

Most Rockies fans are thinking it could take major league ready pitching prospect Esmil Rogers, a former midseason top 50 guy by BA in 2009 but has experienced command issues lately, and a few other guys like catching prospect Mike McKenry, but we know teams don't like giving up a middle of the order bat for just prospects. Just it have to take a guy like Chacin, Iannetta or a top 3 prospect for you guys to be satisfied in a Dan Uggla deal, or would you guys take a quanitity deal of a few of the guys off the Rockies top 20 including Rogers? Remember the quality of the Rockies system, we have a ton of pitching prospects you guys could like.

Don't shoot at the Rockies fan for asking :P.
