We’ve heard about it, but only in whispers like David Forst “floating a concept” to Marcus Semien. No parameters have been laid out for actual consideration nor will it be voted on anytime soon.
The issue is that MLB is tired of the “openers” and “bullpen games” and 5.1 IP starts followed by a parade of 100 MPH throwing relievers. So they are starting a possible future preamble to a potential eventual conversation...about forcing starting pitchers to throw at least 6 IP “or else!”
The questions here are what is the “what else,” what should or shouldn’t it be, and what makes the most sense: no change, a little change (and if so what) or changes so bigly they will rival the ghost runner at 2B in extra innings?
