The proposal is long overdue, and the mythical max of 100 pitches is still a joke, and way overplayed by the media and announcers. The golden era of great arms laughs at this so called magic #.
Anyway, the so called "bullpen" games need to go away immediately. Teams that use this are essentially unprepared and overmanaged....see David Bell, who is a complete joke and the worst mgr I have ever witnessed. If it is going to be 6 IP/100 pitches as a couple of parameters, then I believe 3 ER should be the limit. 5 IP should actually be the min, not 6, as that is what is required for the SP to get the win.
You also need to increase the pitch clock to at least 20 seconds. It is taking a toll this late in the season w/ pitchers losing control and more walks during a game.
