Interesting you bring this up, because I was drafting in the 1st round of my 8 player/12 team keeper league and was struggling between picking A Rios and CarGo. The only negative to CarGo was the depth in the Rockies' OF and the fact that he primarily only faced righties in 2009 so there was a question about the amount of playing time he would get.
I went with Rios... CarGo was gone by my pick in the 2nd round (equivalent of Rd 10 in a redraft).
I find it strange that Rios was the wrong decision even though he has had an outstanding year!
The impetus for my question is the realization that not buying (roto auction) CarGo has cost me the championship in my league. With CarGo (and his contributions in all categories) I would have an insurmountable lead. As it stands, it would take an incredible set of occurrences for me to pull out the win...second or third is most likely.
While one accurate player projection is not enough to cause one to use a particular service/individual, I am (like you) particularly sensitive to my blunder in not getting CarGo and am interested if anyone out there saw this coming...as I might be interested in peering into that same crystal ball in 2011.
