I think a difference is the best pitch framing catchers (IMO, not necessarily according to any stats) are far more subtle than floppers are. For example, compare the "
top 3 catchers in pitcher framing 2023" (their title, not mine) to
Jose Trevino. Notice how the first 3 all often catch the ball first then jerk the ball quite noticeably from one point in space to somewhere else often far away and stop for a good second or two. Then look at Trevino. Notice how far more fluid he is. It's like he has one long arm movement and he just happens to catch the ball in the middle of that motion. And then notice how he usually (sometimes not, but usually) doesn't stop for a long while. It's like he's trusting that he's fooled the umpires instead of begging. I agree, the first 3 catchers, the "top 3", are like floppers, but Trevino is like a master assassin with how good he is. I'm all for the latter and not at all for the first 3.
All more reason to bring in the balls and strikes challenge system however.
