FFS has posted some good pictures of the grip. If you look up the batjack it will explain the What we find out giving lessons , those that don't use the correct grip tend to roll the wrists producing a weaker swing with less bat speed.
The grip I talk about has nothing to do with alignment of knuckles. More the bat in the fingers and hitting against the pad of the top hand.

I'm not so sure I agree. I'm not seeing that here...
But maybe it is happening here...

Maybe it's not an absolute.
Can someone grab the frames at contact?
Still not making proper use of the hands.
