I wasn't really saying the 5D3 couldn't be used for sports just that it will largely depend on the shooters preference. I like having the ability to go higher if I want because sometimes my skill level needs the help. Volleyball being the best example I can think of.
In no way was I impugning your opinion sir, rather illustrating your point. I sometimes wish the 5D3 had 10 FPS too. I have 10 FPS in the 1D3, but it's relegated to seldom-or-never-used backup duty because the 5D3 trumps it in terms of "reach" (via cropping) especially at high ISO (composite is 12.8k ISO). The faster the athlete or action, of course, the more critical FPS become. OTOH xperience has shown that FPS are no guarantee of that elusive "ideal" frame either. As others have noted, timing, positioning, understanding exposure, the sport, PP, etc etc - in short, the other 57 things lumped into technique - are more relevant
