Not everyone dives. I played OF most of my BB career and rarely if ever would dive and yes I know how to.
Sliding catches, running into walls, collisions with other OF (unintentional) I had no fear of any of those. Diving head first for a ball in the air, not really a comfortable thing for me so rarely did it.
I did not have the same aversion to head first slides or dives on base paths which I would use when I felt it was the right call.
Ok - this is just like my DD. She is fearless when it comes to everything listed above. Makes me feel better!
