His free foot gained distance to first and was planted before he release the throw over. I can see that without slow motion.

I saw what Bob saw, in real-time. The question for you, where was his foot when he started his throw?

Saw that!

I repeat, when I get to the "Show", (NOT) then I can call it my way too.
