8fps and AF will let you capture moments in sports, but not necessarily the special moment that takes you beyond the average shot that the 50 shooters next to you get too. With luck the special moment will happen when your AF is on the target and your 8fps frame is fired, but for me my special moments come with manual-focusing and firing one frame. I want the FPS available, but it won't make the shot for me. My brain makes my shot and can make a moment that doesn't exist. Best Sports Stories was a collection of the best sports photos/stories from about 1944-1994 and I have about 30 volumes. Each volume is full of great moments captured on film, but my winning shot BSS 1983 was a moment that I made and it didn't exist in reality, and it's the only moment created by a photographer and not just captured in the volumes I have. YMMV with AF and 8fps, but mine don't.
