Our rankings are meant to be for the rest of the season, as opposed to rankings players based solely on what's happened so far, so players that we feel will bounce back get ranked higher than they might deserve. I believe Rollins is still sitting at 2 because the gap between him and the next SSs in the preseason was so large. I moved him down to 3 in my personal rankings last week, and after being benched for a few games this week, I think I'm going to move him down a few more spots.
I'm well aware of how bad Rollins has been, suffering through his performance on one of my main teams. FWIW, [url="http://www.fangraphs.com/statss.aspx?playerid=971&position=SS"]ZiPS is still optimistic[/url], giving him 10 HRs and 18 SBs from this point on.
