A couple of things..
This year when I went to do my pre-draft rankings the rankings didn't match the yahoo defaults. They were specific to whatever league I was in. This meant that about 40 of the top 100 were middle relievers while Giancarlo Stanton was ranked 156. It made it almost impossible to do a really good pre-rank of my own. Please go back to the old way. I want to do rankings based off where yahoo has players ranked, because this is what the average joe sees. I don't care if Jason Grilli is actually 43 by our league rules. Nobody is picking him there. Thanks.
This is a known issue that was discovered and reported the first week of February. There is currently no ETA for a fix.
