I have asked a long time fraternity brother who has been a long time SABR member, he had no good answer. Why do so many of the young pitchers, even in the big leagues, no longer stride through their deliveries but rather seem to have a sidewards leg kick? Seems to me that it would be additional stress on the pitching arm. Is it because there are now throwers and not pitchers?

It's the new way of teaching, and supposedly reduces stress on the arm, increases velo, etc. Who knows, but if there is solid kinetic energy science behind it, I guess it's better (although it seems to reduce the benefit of the pitcher as a defender and makes them more vulnerable on line drives right back at them).

Skenes is the best visual example for me.
 
So without going into a long description. With regards to mechanics as your front foot plants it braces(or lead leg blocking) so then your top half in simplest terms almost turns into a slingshot.(There is obviously more to it like trunk rotation, mobility, etc) You then throw and tend to fall off/spin off. If your hips stay behind your lead leg thats a key cue to velo.

Lead leg bracing has quickly become one of the go to's in velocity.
