Need Rollins Validation

[great gretzky]

I am 90 percent I am sure of the answer, but work and personal responsibilities have me only keeping a cursory eye on my team right now. I need saves, and I am not inclined to chase them this early, but don't want to fall out of the running. I thought I would be high on power at first, but am now questioning it. Was offered Dunn and Downs for Rollins, which obviously is selling rollins way low. But is it worth even considering? I know we get addicted to names, and rollins is a big one, but I am half-considering this, as I have tried moving choo, abreu, furcal thus far for no results.

mccann (yadier molina)
howard
f. sanchez
furcal
theriot
m. cabrera
g. atkins
c. crawford (got him in a similar trade last year, but reversing sides)
bay
abreu
choo
werth/lind.

10 teams. I feel Dunn and Howard could destroy my average too. Should I ask for Fielder and Downs (I have ryan and frasor)
