It's a pointless rule. It does nothing to grow the game. And to top it off, I hate the idea of any rule that forces guys to keep throwing high stress pitches if/when they aren't dealing. If you've got a guy you want to limit, this needlessly, with no benefit, puts that player at risk. What happens if some Johnny Contact comes up and fouls off 12 pitches? We're going to see a bunch of dudes coming out of games with "something not feeling right". It's just a completely pointless rule.
