Different SP Ranks?

So, I use your Probable Pitchers site to look for whom to start, and the SP ranks under each pitcher is a good asset to help with this… however, when I click on a pitcher and go to their specific page, the SP rank is different ???

Lucas Giolito… on the PP page, his SP rank is 41… on his own page, his rank is 21… can someone explain the difference in the ranking, please ???


I believe the ranks on the PP pages are the VBR ranks for that week’s weekly projections, while the ranks on the player pages are the ROS ECR ranks.
